The three studied groups involved 36 first-grade pupils, 34 older pre-schoolers, and 34 younger pre-schoolers. The average scores of the pupils on all the IDS subscales point to their sufficient school readiness. Objective (IDS) and subjective results (KGSD-R) differentiated the children’s results into high and low, however, the correlations for the pre-schoolers were few and low, and for pupils – not statistically significant.
