2019 was the third year that the Teaching, School, and Principal Leadership Practices Survey (TSP) was available for free use by schools. The questions in this survey draw on a strong body of evidence about effective practices. The TSP asks teachers and principals to rate how often a practice occurs or how well the practice is done. This 2019 aggregate report provides graphs of the frequencies for the items in each of the domains in the Teaching Practices, School Practices and Principal Leadership sections of the TSP. It also provides frequencies for the items that focus on Maori learners, and the items that focus on Kahui Ako (Communities of Learning), along with teacher views of their gains from their Kahui Ako participation. Teacher and principal workload and morale are also shown. Section 1 provides the graphs from teachers' ratings of their teaching practices, and teacher morale and views of their workload. Section 2 gives graphs of teacher and principal ratings of their school practices, and teacher views of what they were gaining from their school's Kahui Ako membership. Section 3 gives graphs of teacher and principal ratings of their school's principal leadership practices, and principal reports of their workload, and support. Section 4 gives demographic information about teachers' roles, and about their and principals' length of experience in their role, as well as at their current school. It also provides a table of the school characteristics of the 2019 respondents, compares these with the national school statistics, and notes some differences in these between the three TSP rounds.
