Validity in teachers’ summative assessments

This paper describes some of the findings of a project which set out to explore and develop teachers’ understanding and practices in their summative assessments. The focus was on those summative assessments that are used on a regular basis within schools for guiding the progress of pupils and for internal accountability. The project combined both intervention and research elements. The intervention aimed both to explore how teachers might improve those practices in the light of their re‐examination of their validity, and to engage them in moderation exercises within and between schools to audit examples of students’ work and to discuss their appraisals of these examples. This paper reports findings, arising from this work, of the research that aimed to study how teachers understand validity, and how they formulate their classroom assessment practices in the light of that understanding. The paper also considers how that understanding might be challenged and developed. It was found that teachers’ attention to validity issues had been undermined by the external test regimes, but that teachers could re‐address these issues by reflection on their values and by engagement in a shared development of portfolio assessments.

Can teachers’ summative assessments produce dependable results and also enhance classroom learning?

Summative assessments that are integrated within the daily pedagogy of teachers are problematic. Some argue that they cannot both be helpful to pedagogy and yield results that are comparable across and between schools. Others claim that there is enough evidence to show that these targets can be achieved. The project described in this paper explored how teachers might enhance their competence in summative assessment in ways which might also have a positive effect on their teaching and learning. A strategy was developed based on five key features of summative assessment practices. The findings, from a longitudinal study with 18 teachers, are based on the teachers’ opinions, both about the quality of the results which they achieved, and about the positive impacts on the involvement of pupils, on collaboration between teachers, and on interaction with parents. The project involved teachers of English and mathematics in three schools, working with the authors, over two-and-a-half years.
