The vmbo (voorbereidend middelbaar beroepsonderwijs, literally, "preparatory middle-level vocational education") education lasts four years, from the age of twelve to sixteen. It combines vocational training with theoretical education in languages, mathematics, history, arts and sciences. Sixty percent of students nationally are enrolled in vmbo. Vmbo itself has four different levels, in each a different mix of practical vocational training and theoretical education is combined.
- Theoretische leerweg (literally, "theoretical learning path") is the most theoretical of the four, it prepares for middle management and vocational training in the mbo-level of tertiary education and it is needed to enter havo.
- Gemengde leerweg (literally, "mixed learning path") is in between the Theoretische- and Kaderberoepsgerichte Leerwegen.
- Kaderberoepsgerichte Leerweg (literally, "middle management-oriented learning path") teaches theoretical education and vocational training equally. It prepares for middle management and vocational training in the mbo-level of tertiary education.
- Basisberoepsgerichte Leerweg (literally, "basic profession-oriented learning path") emphasizes vocational training and prepares for the vocational training in the mbo-level of tertiary education.
- Praktijkonderwijs (literally, "practical education") consists out of mainly vocational training. It is meant for pupils who would otherwise not obtain their vmbo-diplomas. After obtaining this diploma pupils can enter the job market without further training.
For all of these levels there is Leerweg Ondersteunend Onderwijs (literally, "learning path supporting education"), which is intended for pupils with educational or behavioural problems. These pupils are taught in small classes by specialized teachers.
