In this study, the implementation effects of a programme for the train
ing of coaching skills with Dutch school counsellors ave described. Th
ese school counsellors are expected to provide help and support to pri
mary school teachers. Coaching is a form of in-class support intended
to provide teachers with feedback on their own functioning and thereby
stimulate self-reflection and self-analysis in order to improve instr
uctional effectiveness. To assist school counsellors in their attempts
to coach teachers, a training programme was designed: 'The school cou
nsellor as coach.' A quasi-experimental treatment-control group invest
igation was then set up to test the effects of this programme. Based o
n the pre- and post-training ratings of coaching conferences, a signif
icant treatment effect was found for the coaching skills concerned wit
h the development of autonomy (empowerment), feedback, and purposefuln
ess. The pre- and posttraining ratings from coached teachers showed no
significant treatment effects. This was because the teachers were not
accustomed to in-class assistance and thus rated the coaching skills
of the school counsellors quite favourably even at pre-test.
