In order to test whether the HAND in HAND programme had a positive effect on the SEI competencies of students and school staff (and an inclusive classroom climate), we tested the effectiveness of the HAND in HAND programme in experimental conditions.
Following a prior measurement (HAND in HAND assessment) of the SEI competencies, a group of students (and their school staff, principals and other school staff) were subjected to the HAND in HAND programme (in several different conditions). After the HAND in HAND programme had been completed, the SEI competencies of these students and school staff were compared to the SEI competencies of students and school staff who have not participated in the HAND in HAND programme.
The experiment was planned to be carried out in the same way across all of the countries conducting the HAND in HAND field trial: Slovenia, Sweden, Croatia and Germany. Strict procedures were followed (for sampling, implementation of the field trials, evaluation, and quality assurance).
