Vocational school (Haarlem)

A century later, when the Industrial Revolution came to Haarlem, the need for qualified staff was felt more and more by local businesses struggling to keep up with the times.

To help such schools concentrate on the practical lessons, the law for compulsory education (leerplicht) was passed in 1900 for children aged 6–12.

Some of the "extra class" names in the Household school were ‘nat en droogwaschen’ (wet and dry-cleaning), ‘strijken’ (ironing), ‘tafeldienen’ (waiting tables), ‘naaien van lijfgoed’ (sewing underwear) and ‘koken' (cooking) for workmen's wives.

In need of more space for the practical lessons, the Ambachtsschool expanded and in 1919 the "Middelbare Technische School" (MTS) opened on the Verspronckweg.

After the war, it became the "Hoger Technische School" (HTS), and the young students were taught how to fix trams, trains, and airplanes.
