Education in States and Nations: 1991
Staff are underestimated because staff in institutions consisting of preprimary grades only are not taken into account.
The figures are estimates. Teaching staff at continuation schools are included in other staff.
The apprentice teachers -- i.e. the staff responsible for the teaching of apprentices in the enterprises under the dual system -- are not included among the teaching staff.
The figures are underestimated because they do not include teachers in schools that have only preprimary childhood classes. Many of the schools included here offer both preprimary (i.e., pre-kindergarten and kindergarten) and primary levels of education.
State-level figures are available for private school teachers, but not for non-instructional staff. Non-instructional staff for private schools were estimated using a national teacher-to-non-instructional staff ratio for private schools.
