The study tried to evaluate the performance of experimental educational projects, supposed to fill the gap between lower vocational training ( LBO ) and lower secondary education ( MAVO ) on the one side and middle vocational training ( MBO ) or skilled employment on the other side. These projects are referred to as KMBO, Kort Middelbaar Beroeps Onderwijs ( short intermediate vocational training/ a 2-year full-time curriculum for the age- group of 16-18 ) and BBO, Beroeps Begeleidend Onderwijs ( job coaching education/ a part-time vocational training for youth already employed ) for comparison. Main criteria for evaluation were: 1. selection of pupils: do the projects attract and select the people they were set up for? 2. the fit between the education or training offered and labour market demands. A four point panel survey design was used in order to monitor school career and job career of 961 pupils, split in 2 year-groups ( cohorts ). Measurements took place in september 1981 ( N=961 ), may/june 1982 ( N=63, drop-outs only ), september/october 1982 ( N=742 ) and september-november 1983 ( N=709 ). The archived file combines all these measurements.
