In September through November 2020, we asked families of children included in the Epipage 2 study to participate in a school survey for fourth-year primary school (CM1) classes. 

This survey, initially planned between May and July 2020 (end of Year 3), was postponed after the lockdown and then partial reopening of schools. 

Nonetheless, the particular conditions of schools in recent months and the difficulties encountered by some families make an evaluation of the learning supposed to have been acquired by the end of Year 3 (CE2) even more relevant.  

This new stage is conducted jointly with another epidemiologic birth cohort study that began with ours: Elfe (French longitudinal study from childhood, has been following up the children born at term in 2011 with methods similar to those of Epipage 2. We will be focusing on your children's learning in its entirety, including its success, orientation, and school problems, as well as interaction with other children. 

Our long-term objective is to provide public authorities and education professionals with new food for thought about, for example, the effects of schooling on children's development.  

The authorities of each academic district, school heads, and teachers were informed early on about this survey, which was authorized by the Ministry of Education.  

Practical Aspects

  1. Collection of the addresses of schools attended by children in the Epipage-2 cohort  
  2. In the second half of 2019, we contacted you (by email or regular mail) to find out what schools should participate in this survey. More than 1860 families responded favorably to our request, enabling us to ask more than 1400 schools to participate.  

    If your child changed schools in September 2020, please tell us so soon ( This email address is being protected from spambots. You need JavaScript enabled to view it. ). 

  3. Information for the schools  
  4. In May 2020, we wrote to the school heads and teachers, with posters presenting the survey to them. 

  5.  Mailing of evaluation material to schools and workbooks to parents  
  6. In mid-September 2020, we sent workbooks for the children directly to the schools. At the same time, we sent parents a mailing with information accompanying the evaluation form to be transmitted to the teachers. 

    A letter for your child was also included in this mailing.  

    The material for this survey informed the school principal only that a child belonging to one of these two cohorts is present in her school, without mentioning which cohort, so that your child's preterm birth is not made public, if you prefer. For reasons of confidentiality and to maintain anonymity, your child's name was not communicated to the school.For reasons of confidentiality and to maintain anonymity, your child's name was not communicated to the school.  

  7. Evaluations  
  8. Teachers conducted these evaluations between September and early November 2020.

    Presented as illustrated workbooks attractive to children, the activities proposed took 90 minute to do and were simple for teachers to implement during class.  

    These exercises were done in small groups that included simultaneously the children in the Epipage 2 cohort and some classmates, to prevent stigmatization of the children born preterm .  

    The teacher sent your child's results directly to us, using the evaluation sheet you transmitted to him/her. If you want, the teacher can return your child's workbook to you and tell you how these activities went in class.  

    When the results for the cohort are known, you will receive a report about this survey.
