Abstract
The Performance Assessment for California Teachers (PACT) is a high stakes summative assessment that was designed to measure pre-service teacher readiness. We examined the inter-rater reliability (IRR) of trained PACT evaluators who rated 19 candidates. As measured by Cohen’s weighted kappa, the overall IRR estimate was 0.17 (poor strength of agreement). IRR estimates ranged from −0.29 (worse than expected by chance) to 0.54 (moderate strength of agreement); all were below the standard of 0.70 for consensus agreement. Follow-up interviews of 10 evaluators revealed possible reasons we observed low IRR, such as departures from established PACT scoring protocol, and lack of, or inconsistent, use of a scoring aid document. Evaluators reported difficulties scoring the materials that candidates submitted, particularly the use of Academic Language. Cognitive Task Analysis (CTA) is suggested as a method to improve IRR in the PACT and other teacher performance assessments such as the edTPA.
Highlights
Teaching performance assessments (TPAs), such as the Performance Assessment for California Teachers (PACT), were mandated by the California state legislature in 1998 in response to a perceived need for teachers, and teacher education programs, to be held more accountable for the teaching skills and expertise brought to the K-12 classroom
Even though the PACT has been discontinued as a TPA at our institution, it has evolved into the edTPA, which is used nationally at several institutions, including our own
Because we cannot access the double-scored data behind the scores for our edTPA candidates, it is impossible to assess inter-rater reliability (IRR) using the methods we used in this study
Summary
Successful education systems are complex and require classroom teachers who demonstrate a broad range of competencies [1]. One way to increase the potential of placing competent teachers in classrooms is through the performance assessment of teacher candidates. Novice teacher competency is assessed within teacher preparation programs, and frequently, in the United States, by state-mandated assessments of teacher performance. To effectively assess candidates’ readiness to teach, these assessments need to be used in a manner that optimizes transparency, authenticity, validity, and reliability. Teaching performance assessments (TPAs), such as the Performance Assessment for California Teachers (PACT), were mandated by the California state legislature in 1998 in response to a perceived need for teachers, and teacher education programs, to be held more accountable for the teaching skills and expertise brought to the K-12 classroom. Like exit exams in law and medical school, an exit exam in schools of education was suggested so as to raise the stature of the teaching profession among other professions [2], and to improve the quality of teacher education programs
