Using assessment data to improve teaching requires several steps: 1) Teachers need high-quality assessment data that provides detailed, curriculum-relevant information about what students know and can do. 2) Teachers must develop their knowledge and skills to properly interpret the assessment data and understand how to adjust their teaching practices to address student needs. 3) School leaders need to support teachers by helping them unpack assessment data meanings and leading discussions on changing teaching approaches. Effective use of assessment data for instructional improvement is a complex process that requires ongoing professional development to build teachers' knowledge and skills over time.

1. Using
assessment data
for improving teaching practice
For teachers to respond to student learning needs they need
detailed information about what their students know and can
do through high-quality assessment data, but they also need
opportunities to develop their knowledge as they delve into the
assessment information, says Helen Timperley.
