This paper reports how consultative work with teachers can be supported by the use of letters. Letters were written by an educational psychologist (EP) after a consultation meeting with a teacher. Features of therapeutic letter writing and solution-focused brief therapy were used to increase the collaborative intent of the letters. Follow-up questionnaires indicated that teachers valued this kind of letter highly, rating it as contributing to over 50% of the positive impact of EP involvement. There is discussion of the role consultative letters play in the joint work of teachers and EPs.
