Most schools have two or three school leaders, but the largest schools generally have three or more. For example, in general secondary education, a large school of more than 1 500 students can have one principal, 2 or 3 deputy principals, and various secretaries, while a small school of less than 500 students can operate without a deputy principal. Small rural primary schools may only have one teacher that also fulfils the leadership role according to a special teacher statute (maestro director), which requires teachers to devote 25 hours of their time to teaching, and 15 hours to school leadership and management (INEEd, 2015).
