Non-PRO Spanish to English Other Education / Pedagogy

Hello

Would anyone be able to explain what these are, please? I'm having a go at translating what I'd describe as a course outline for a degree at a university.

They are used in the following context:
Asimismo, el plan consta de dos niveles: Nivel de formación Básica que se establece en los primeros 5 semestres ....y el Nivel de concentración que comprende del 6o al 8o semestres

Thanks!
