Thurnage Appendix

[Not up to date... yet.]

Article 1

These rules, which are an appendix of the main rules (RI) of the DG, define the modalities according to which the DG deals with the room assignment, called "thurnes" below, of the dormitories, dedicated by the school administration to students.

Article 2

The word thurne can be spell in two ways : turne and thurne. The spelling turne is only allowed during leap years when it is recommended. The spelling thurne is always allowed. The same rule applies for every word including the root thurne.

Article 3

The DG deals with housing of students, as defined by article 3 in the main rules. It also allows other students housed by the school to attend Partial Turnover (partial room distribution) to change their thurne.

General rules

Thurnes Management

Article 4

The DG manages the rooms with the administration. Before every partial turnover, it gives to the DG the list of available thurnes. The DG manages room assignment only : it cannot manage the full housing stock.

Article 5

CROUS rooms or studios can be given to the DG by the administration. They are called exthurnes in the current rules.
These exthurnes are managed by the DG in the same way than thurnes. However, the CROUS can have access criterias (status, nationality, etc.) to the person housed in an exthurne, the DG then has to forbid the choice of this exthurne during general and partial turnovers to every person who doesn't fill the criterias.
According to the administration, the DG can declare some exthurnes of « prioritary occupancy » . They are then distributed specifiquely, as defined in article 25 of this appendix.

Article 6

Every student trading directly with the administration without the DG agreement would be considered as a fraudster, with all the implied consequences, as defined by article 48 of this appendix.

Article 7

The choice of a first-year student not to be housed is irrevocable for the DG. A first-year student who quitted the dormitories and who wants to be housed again should have to do go through a partial turnover (partial room distribution). The case of someone who had to quit the dormitories for health reasons would be dealt on a case-by-case basis by the DG.

Article 8

Every student has to fill their scolar situation for next year to the DG (it can be a gapyear or next year of scolarship).
It has to be done every year before the publication of the jokers list. The DG remimd this duty to students during the inscription to the TG (general repartition). The DG considers that students who didn't answered are going to their next year of scholarship The DG is not responsible for an error about the situation of a student who did not fill their situation. In case of a half-gapyear, students are allowed to choose to declare themselves in gapyear or not, with the limit of two gapyears din their scolarity.

Priority system

Article 9

Every student has, since the first TG happening during their schooling, a certain amount of jokers that can be played during all schooling. They can be played at every moment, together or not. Played jokers are valid until the next TG excluded. Jokers are strictly personal and non-transferable. A joker played cannot be given back, with the exception of the cases defined by the current rules (article 42).

Article 10

First year students don't have any jokers before the first TG of their schooling.
Since their first TG, students have as much jokers as their number of schooling year minus one. As a consequence :

Article 11

Every sabbatic year implies the giving of one joker, if it is proved that this sabbatic year is spend near Paris. An inscription to the TG is such a proof. Especially, every "normalien·ne·s étudiant·e·s" doing a 4th year near Paris is given one more joker.

Article 12

In order to define the priority order for students to choose their rooms during TG and TP, a priority system is set. It defines the number of jokers played and then the number of former years housed (AL) A year is considered housed only if a thurne was obtained during the TG or during a TP before the end of october, with the exception of first year of schooling. The students are set in categories and sub-categories according to an order defined in article 15. They are then sort inside every sub-category by randomization, made through a public algorithm.

Article 13

During a room repartition, if two persons (or three) are in position to get a thurne and have played at least a joker by person they can ask to play by pair. A pair (or a trio) is considered as one in the sorting, with a number of joker equal to the sum of the number of its members. With an equal number of jokers, pairs are prior to individuals, and trio to individuals, and trios to pairs. The order of pairs (or trios) with the same number of jokers is set by randomization.

Article 14

Trios are inseparable and united for a year.

Article 15

The order of categories during repartitions is the following, with the following notations : T for trio, P for pair, J for joker and AL for year of housing : Categories S, PÉ and A (who are not students as defined by article 3 of main rules), as F, cannot play during the TG. As a consequence of article 9, first year students are considered as 0J.0AL.

Article 16

Are considered « CROUS grant holders » every student, as defined by article 3, whose name is written on a list of persons who need to be housed on social criteria that the administration gives to the DG. Can also be considered "CROUS grant holder" students who have gave directly to the DG their grant attestation for the upcoming year.
The DG has a secrecy duty to persons having the status "CROUS grant holder", in particular the DG has to keep their status secret when it doesn't have their written agreement.

Article 17

The SI and CROUS grant holders are garanteed to have a thurne during the TG if they play at least a joker ; unless they ask explicitely the DG and fill a form, they can only play one joker a year. In the case one student of these categories would like to play more than one joker, the DG only agrees after ensuring that the student understand that they may no be housed the year after. The form to declare that the student understands the risks should be given before the publication of the list of jokers. The DG remembers this obligation to SI and CROUS grant holders during the inscription to TG.

Article 18

If a student doesn't withdraw the key of their room during the month after its availability (or the month after the beginning of the school year, if concerning the TG) and didn't inform the DG, the thurne is automatiquely considered free.

  • The "normalien·ne·s élèves" have 3 jokers to play during all their schooling.
  • The "normalien·ne·s étudiant·e·s" have 2 jokers to play during all their schooling.

Thurnage général (TG)


Article 19

The date of the thurnage général (TG) is determined by the DG, under the same modalities of the date of an AG (article 17 of main rules).

Article 20

At the end of every school year, the DG organizes a TG during which its attributes rooms for next year to students (as define by article 3 of main rules) who would be in second, third or fourth year (or in sabbatic year before their last year), blocking a certain amount of rooms in every site with the agreement of the administration in order to house first year students and students from abroad. No other quota is fixed for other categories of students of whose housing depends of the school administration.
During summer, the DG gives to first year students, and to students from abroad the rooms blocked for this case. The thurnage of first year students is finished when all first year students and students from abroad are housed.

Article 21

To enroll, every student should fill the form through the website of the DG at least 10 days before the TG. In case of misworking of the website, emails are also allowed. The person whose answers are given to the DG after the deadline are exposed to see their wishes ignored and will be systematiquely ranged the latest of their category.

Article 22

The DG determines the number of thurnes available during the TG in agreement with the administration in order to let enough rooms free for first year students and students from abroad during the beginning of the school year in september. Especially, the DG negociates the repartition of PE in each site with the DRI. The DG has to estimates the number of first year students who don't want a thurne, in order to both not let a too big amount of rooms free after the first year students distribution, and to allows every first year student who wants a thurne to have it. Between the TG and the first year students' thurnage, the DG makes its estimation better as long as its receives rooms' demandst, and, if possible, gives thurne to non housed persons, respecting the order of the TG. The DG can then garantee housing to grant holders whose grant attestations were given after the deadline defined in article 25. The DG doesn't have to give rooms if concerned students don't answer within one week.

Article 23

Through DG's website, students fill their status and commit to the TG. Theya announce the number of jokers played for the next year, and precise if they want to play by pairs or trios. Person who are CROUS grant holders are advised to : Once inscriptions are closed, the ranking is made and pairs are created according to articles 12, 13 and 15, with an iterativ way. The number of jokers played cannot be modified. The random draw is public and reproductible. The reproductibility informations of the random draw are published. The DG then gives CROUS rooms according to wishes given by CROUS grant holders students, as defined in article 25. The ranking, where do not take place students having or having refused a CROUS studio and withdrawing persons is published. Steps describe in previous alineas are done one by one, in this order.

Article 24

The calendar of the TG organization have to respect the order and the deadlines which follow :

Article 25

The distribution of CROUS rooms to CROUS grant holders happends as described below : No grant attestation, as defined by article 16, could be take into account by the DG for the TG after the attribution of CROUS rooms.

  • If they rather get a CROUS room than a thurne.
  • If they rather no be housed than get a CROUS room.
  • At least 21 days before the TG : announce of the TG.
  • At least 10 days before the TG : end of the inscriptions.
  • At least 7 days before the TG : random draw.
  • At least 4 days before the TG : the ranking is made public.
  • First, receive a CROUS room students who said "I prefer a CROUS room", respecting the order of the random draw.
  • Then, if their is still unocuppied CROUS rooms, they are given to the last CROUS grant holders of the draw. If a CROUS room appends to be given to a person who said "I would rather not be housed than be in a CROUS studio", then this person isn't housed at the beginning of the school year, and the jokers played are given back.


Article 26

The TG happends as follow :
the DG members remembers the way the thurnage works. Every student, or pair, or trio is called during its turn according to the ranking to choose its thurne among them free. The DG doesn't have to give a thurne to an unreachable person and who doesn't ask to be represented.
The DG makes sure ate every moment that the number of free thurnes its can still give, which are not reserved as defined by article 20, is greater than the number of students who have garantee of housing (SI included) who have not a thurne yet. When these two number are equal, the DG ends the TG.

Article 27

The DG has to publish TG results within 24 hours after its end, on its website and on its board.

Article 28

After the publication of TG results, the DG gives thurnes with secrecy to CROUS grant holders who didn't get thurnes during TG.
If priority CROUS rooms are still available, they are distributed in priority.

Article 29

Students who didn't get any thurne neither during TG, nor before the housing of first year students, get back their jokers.

Article 30

Every missing student during TG can be represented by another student, if they has tell the DG so (written procuration or email sent directly to the DG, or precised in their wishes). A student can also be represented by the DG, under the same terms. If a student is not represented, DG members choose the thurne. The DG isn't responsble of the consequences of the missing of a student in a thurnage.


Article 31

If a person who had a thurne during the TG finally chooses not to take it at the beginning of the school year, they can get their played jokers back. The current year then doesn't count as an housed year. This is allowed only if the abandon of the room happens before the announce of the first partial distribution of the year, and if the thurne can be redistributed after that. After that date, played jokers are so definitively.

Article 32

During the period beginning at the TG and ending at the first partial distribution, a pair formed for the TG can choose to broke. The DG then give a thurne to each member of tge pair in priority. It can give the thurne first got to one of the member of the pair if and only if this member could have got an equivalent thurne alone during the TG.

Article 33

After the thurnage of first year students, the thurnes which are still free are given before the beginning of the school year during the first partial distribution.

Partial distribution (TP)

Article 34

During the school year, the DG gives thurnes during partial ditributions which happens every month.
After the TG, and entil the closure of the rooms for summer, no TP can be done. The free rooms are then given according to DG's choice.

Article 35

The DG can choose to garantee a room to a CROUS grant holder or to a first year student who didn't ask fir a thurne ate the beginning of the school year, at the beginning of the school year, independently of their ranking.


Article 36

The DG chooses the date of TP according to rooms' freeing. It has to : The date choosen for a TP should satisfy to the same conditions than an AG's date, (article 17 of the main rules), with the exception of the TP before the beginning of the school year in september.

Article 37

The annonce of a TP should happend at least a week before the TP. An announce should be published in the student's newspaper. The list of the free rooms if put on the website as soon as possible.

Article 38

If a person who got a thurne by creating a pair with another person plays during a TG, they can either : A person who has just broke a pair has the right to form immediately another pair with someone else.

  • Make a TP during the month after the beginning of the school year, in order to give free thurnes among them reserved to first year students.
  • Make at least a a TP every month, as soon as some thurnes are free.
  • Paired again with the same person ; the pair is still considered as one person during the TP.
  • Broke the pair.The two members of the pair then have to play to the TG in order to be prior housed, and their thurne is considered free. If the number of jokers played by one members of the pair is considered high enough, the assembly can unanimously gives a derogation and let one member of the pair keep the thurne.


Article 39

Every housed person, student or not, can play during TP to change their thurne. The ranking ordre during TP is defined by articles 15 and 40.

Article 40

During a TP, if there is at every moment the same number or more first year students not housed in Ulm (carré excluded) than thurnes in Ulm (carré excluded), then first year students are prior for thurnes in Ulm (carré excluded), until there is no more free thurne in Ulm.

Article 41

During a TP, every student who has already been called (and then with a better rank than the student who is now choosing) can "appeal", which means ask for a thurne which became free after their turn. They then frees the thurne choosed before. The TP is then iterative.

Article 42

A TP takes place as described below : If a person plays jokers during a TP but doesn't get any thurne or keeps the same thurne, their jokers are given back.

Article 43

A student unable to assist to a TP can be represented either by the person of their choice, or by the DG, as defined by article 30.

Article 44

At the beginning of TP, the ocuppants of two thurnes can present themselves to the assembly to exchange their thurnes. For every case, if the assembly agrees and the DG members think the exchange is sensible, (especially that the two rooms are equivalent) then the exchange is immediately made and written in the result of the TP. The person who are part of the exchange are allowed to play during the TP.

Article 45

In case of construction work which implies the closure of occupied rooms in one the school location, the DG has to garantee, as much as possible, a new housing to people concerned by construction work. To do so, the DG can forbid new students in these rooms during TPS before the beginning of the construction work, or male prior moved persons.

  • The DG member call every person present or represented, by category. The call begin after agreement between present and DG members. After this moment, no more inscription or change of situation is accepted.
  • A random draw is made to order students in every category acording to article 15.
  • Every student is then called, at their turn. They chooses either to pick a free thurne, nor to keep their thurne. When a thurne becomes free, either it is picked by someone already called, (potential conflicts are fixed in order of calling), nor it is write as free.

Particular cases

Article 46

If the health of a student needs a particular care, the DG can allows they to occupy a thurne according to conditions outside of these rules, which are defined case by case, with dialogue with the concerned administration.

Article 47

Every student is allowed to live in their thurne with another person of their choice, Howerver, they have to declare this roomate to the DG, which allows the release of second key, and a card if necessary. It allows first to favorize the recognition of these housed persons, and also to limit the risk of confusion with subletting problems. A long absence of the housing person is for the DG a subletting case.


Article 48

All actions going against the rules presented are considered as a fraud.

As frauds, we consider, for instance: setting an under-occupation contract (even for free) with a person who is an ENS student or not, using a room as a secondary residence, the fact, for members of a pair, they do not declare their quitting the dorms, exchanging rooms with one another without the DG knowing, false declaration of situation or of jokers amount, all kinds of seeking to avoid the DG in its role of rooms distribution. The foregoing list is not exhaustive.

Exchanging rooms without declaring is strictly forbidden, and considered as under-occupation.

Article 49

[to be translated]

Les fraudes peuvent être de trois types, appréciées selon les circonstances dans lesquelles elles ont été commises :

  • Simples, qui sont faites par erreur et sans intention dolosive ;
  • Graves, qui sont faites en connaissance de cause, mais sans intention dolosive ;
  • Lourdes, qui sont faites en connaissance de cause, avec intention dolosive.

La fraude entraîne une sanction proportionnée à sa gravité.

La DG prend en considération la situation personnelle de la personne mise en cause, ainsi que toute autre circonstance qui serait de nature à amoindrir ou accroître la gravité de la fraude.

La sanction n’est pas valable dès lors que la DG l’a adoptée sans avoir proposé par voie électronique un entretien préalable à la personne intéressée.

En tout état de cause, la DG sanctionne au maximum :

  • La fraude simple par l’attribution d’un classement plus bas que celui de l’ensemble de la catégorie à laquelle appartient la personne intéressée pendant au moins un an ;
  • La fraude grave par le retrait d’un joker ;
  • La fraude lourde par la permission de ne participer aux thurnages généraux et partiels qu’en tant que dernier classé.

Article 50

[to be translated]

La DG peut adopter des mesures conservatoires. En particulier, elle peut demander à un occupant irrégulier de quitter sa thurne lorsque l’occupation est effectuée sans titre.

Article 51

[to be translated]

Le cas échéant, la DG prévient la Direction de l’Ecole, qui est en mesure de prononcer des sanctions pécuniaires ou de saisir la juridiction compétente pour connaître du litige.

Article 52

[to be translated]

En cas de contestation, une personne sanctionnée peut faire appel de la décision prise par la DG devant la prochaine Assemblée générale, ordinaire ou extraordinaire. Il est possible de convoquer un Assemblée générale extraordinaire dans ce seul but.

Dans ce cas de figure, les sanctions sont suspendues dès lors que l'AG est convoquée et la DG présente en ouverture d’AG les griefs qui sont reprochés à la personne intéressée. Cette dernière se voit accorder un temps de parole raisonnable (dix minutes au moins) pour présenter sa situation à l’AG. Elle est assistée de la personne de son choix.

Après débat, l’AG vote à bulletin secret en faveur du maintien de la sanction prise par la DG, d’une sanction moins lourde ou de l’annulation de la sanction.

Article 53

The DG congratulates all persons who read these rules entirely.
