Teacher certification

What teacher certification actually measures, why it is not the same as teaching quality, and how to interpret the figure.

Definition

Teacher certification (certifiedTeachersPercent) is the share of teachers (in full-time equivalents) who hold a Swedish teaching licence (lärarlegitimation) and are qualified to teach, where qualification covers the school type, subject and, in compulsory school, the grade band of the teaching they do.

  • Teaching licence — issued by Skolverket after completing a teacher education programme. Required for permanent employment.
  • Subject certification — subject-specific. A licensed Swedish teacher is not automatically certified to teach mathematics.

The metric comes from Skolverket's official statistics on teaching staff. The figure refers to teachers in post on 15 October. Only teachers in subjects and at school units that require a teaching licence are counted, and in upper-secondary school subject qualification is only assessed for a selection of subjects.

How to interpret

100 % certification ≠ good teaching. Certification measures formal qualifications — whether the teacher has a licence and is qualified for the teaching. It says nothing about pedagogical skill, engagement or classroom leadership.

Read alongside student outcomes. If a school has high certification but low results (e.g. low merit value or a negative SALSA score), other factors are at play.

Subject distribution varies. Nationally, the greatest shortages are in mathematics, science, mother tongue instruction and Swedish as a second language. A school may have 90 % overall certification but 0 % in mathematics — the aggregate figure hides subject-level gaps.

School type matters. Municipal schools generally have higher certification (~73 %) than independent schools (~65 %). Rural schools often have lower rates than urban schools due to recruitment difficulties.

Common mistakes

  1. Assuming certification = quality. Certification is a necessary but not sufficient condition. Uncertified teachers can be skilled, and certified teachers can be mediocre.
  2. Ignoring subject distribution. The aggregate figure can hide serious shortages in individual subjects — ask for subject-specific data if available.
  3. Comparing without regard to school type. Independent schools generally have lower certification, partly due to different employment conditions and recruitment strategies.
  4. Overlooking substitutes and temporary staff. The certification figure is a snapshot of the teachers in post on 15 October, so a substitute post or fixed-term appointment at that moment can move the value, especially at a small school.
