Interviews/Focus Groups
In addition to the teacher survey, the internal coherence assessment requires a set of interviews, and optional focus groups, that serve three purposes: (1) to corroborate, with the voice of teachers, some of the broader themes and findings of the teacher survey; (2) to provide direct evidence from school leaders, who are not included in the teacher survey, on the major dimensions of the internal coherence framework; and (3) to provide specific contextual information about the school that is useful in understanding its school improvement work. Currently, the selection of teachers for both interview and observation is left to the discretion of the principal. Because of the small sample size (typically 4-6 teachers are interviewed and 4-6 observed, with the possibility of overlap) results of this component of the diagnostic serve purely for the learning of the research team and district leadership: interview data is not reported back to administrators in schools.
