According to the Education Act, it must be an appropriate composition of children in each group of children. A guide that according to Magdalena Karlsson at the National Agency for Education is not particularly clear.

- Because the school law is not always clear, we write general advice with comments as an extra support for how to think.

Common advice

According to the general objectives for goal attainment in the preschool, there are a number of advice that the principal and the principals must fulfill. The comments on this include benchmarks on how many children are suitable in different age groups.

- The councils must meet the chiefs if they cannot prove that another way is more appropriate. But the comments are just a benchmark without legal bearing, says Magdalena Karlsson, Education Council at the National Agency for Education.

No research on the basis of benchmark

But the question is what the recommended figures are based on. Does it matter if there are 15 or 20 children? No research is based on, for example, 15 children being optimal.

- What the research showed was a number of other factors that play a role in determining the size of a group.
