Monitoring and evaluation (M&E) are essential management tools for any educational programme or project. This booklet compiles 13 research instruments used in the regional study on the use of language(s) in classrooms in ethnolinguistic communities. The tools can be used by programme personnel such as teachers, programme coordinators, supervisors and administrators. The interview guides and questionnaires in this publication can be used to collect relevant information about different aspects of an MLE programme, for 1) the initial programme planning, and 2) later monitoring and internal evaluation of the programme's progress. This booklet complements the five booklets of UNESCO's "MTB MLE Resource Kit -- Including the Excluded: Promoting Multilingual Education (2018)." [For the resource kit, see ED606227.]
