The deux mènent to some careers of engineer, but not by the same chemin. the ENSA vise the State Engineer in 5 ans of a bloc, on entrance exam. The FST commence by a Bachelor's degree in 3 ans, on application, with a specialization progressive. Voici how choose according to your profil and your average.
Passes-tu the threshold ENSA of your stream?
Between your grades of Bac: Orka te situe by rapport at the threshold ENSA — and you indique if the FST is a best pari.
ENSA and FST: deux logiques different
ENSA
Cycle unique of 5 ans (prépa intégrée + engineering cycle). Tu entres with a objective clair: the degree of State Engineer. Accès on preselection national puis entrance exam écrit.
FST
Bachelor's degree Sciences & Techniques (LST) in 3 ans with tronc commun (MIP, BCG, GE-GM…), puis engineering cycle intégré or Master's degree. Accès on application, without entrance exam.
Table comparatif: ENSA vs FST
| Criterion | ENSA | FST |
|---|---|---|
| Degree visé | Engineer of State (Bac+5) | Bachelor's degree Sciences & Techniques LST (Bac+3), puis engineering cycle or Master's degree |
| Duration | 5 ans of a seul tenant (prépa intégrée + engineering cycle) | 3 ans (LST) + 2 ans (engineering cycle / Master's degree) |
| Accès | Preselection national (75/25) + entrance exam écrit | Selection on application (average of the Bac), without entrance exam |
| Sélectivité | High — voir the thresholds by stream | Average — ~11 000 places, tronc commun sélectif |
| Structure | Spécialité choisie tôt, cursus cadré | Tronc commun (MIP, BCG…) puis specialization progressive |
| Ideal if… | Tu passes the threshold and tu veux a chemin direct and garanti | Tu not atteins not the threshold ENSA, or tu préfères a parlesson modulaire / a Master's degree |
Sélectivité: that do if you ratez the threshold ENSA
Beaucoup of students scientifiques not passent not the plancher of preselection ENSA (surtout in PC and SVT, where it monte to 14-15). In this cas, the FST is a plan B solide: it mène at the same type of carrière, with a year in addition, and te laisse rejoindre a engineering cycle or a Master's degree ensuite.
Checks your position with the guide of the threshold ENSA and the selection FST.
Débouchés and further study options
- ENSA → engineer in entreprise from the sortie, secteurs industrie / IT / energy / BTP.
- FST → LST puis engineering cycle FST, Master's degree, or entrance exam on titre towards of other schools.
- The deux ouvrent the voie at the PhD and to the recherche.
How décider
Tu passes the threshold ENSA and tu veux a chemin direct → ENSA.
Tu not passes not the threshold, or tu préfères a parlesson modulaire / a Master's degree → FST.

Frequently asked questions
Equals-it mieux do a ENSA or a FST?
If your weighted average dépasse the preselection threshold ENSA of your stream and that you voulez a degree of State Engineer in 5 ans without risque of réorientation, the ENSA is more directe. The FST is a very bon choice if you not atteignez not the threshold ENSA, if you préférez start by a Bachelor's degree (LST, 3 ans) before of you spécialiser, or if you visez a Master's degree universitaire.
Can-we devenir engineer in passant by a FST?
Oui. After the Bachelor's degree LST (Bac+3), the FST proposent some engineering programs intégrés and some masters. We can also candidateer to some engineering schools on titre. The parlesson is simplement more long and modulaire that the accès direct in ENSA.
The FST is-it sélective?
Oui, but less that the ENSA. The FST recrute on application (average of the Bac) via CursusSup and propose environ 11 000 places at the level national. this is more sélectif that a Faculty of Sciences classique (accès libre), but nettement less that a entrance exam of engineer.
