The Foundation was behind the 16 December 1942 Act mandating the "prenuptial certificate", which required all couples seeking marriage to submit to a biological examination, to insure the "good health" of the spouses, in particular with regard to sexually transmitted diseases (STD) and "life hygiene". Carrel's institute also conceived the "scholar booklet" (""livret scolaire""), which could be used to record students' grades in French secondary schools, and thus classify and select them according to scholastic performance. Besides these eugenic activities aimed at classifying the population and improving its health, the Foundation also supported the 11 October 1946 law instituting occupational medicine, enacted by the Provisional Government of the French Republic (GPRF) after the Liberation.
