This API restores the return to employment rate for jobseekers leaving training since January 2013. It measures the proportion of trainees enrolled in the Employment Unit who, within six months of completion of training, have: • Returned to paid employment of one month or more (excluding private employers, public employers, employers abroad and temporary assignments of uninformed duration) • Or benefited from an assisted contract, • Or set up their business. The API returns five possible values: • 0.2 • 0.4 • 0.6 • 0.8 • 1 These values correspond to a quintile distribution of training according to their level of return to employment. Thus: • 0.2 indicates that training is one of the 20 % of training with the lowest return to employment rates • Value 1 indicates that training is one of the 20 % of training with the highest return to work rates • The rate of return to employment is divided into four geographical grids: employment basin, departmental, regional and national. Training sectors with fewer than sixty outgoings at the national level are excluded from the results. In addition, the results at the geographical mesh level are given only for training sectors with more than 60 outgoings at the grid level. More details on: https://pole-emploi.io/data/api
