In 2010, the authors developed, tested, and released a reliable and valid instrument that can be used to assess the quality of inexperienced teachers’ TPACK by examining their detailed written lesson plans. In the current study, the same instrument was tested to see if it could be used to assess the TPACK evident in experienced teachers’ planning in the form of spoken responses to semi-structured interview questions. Interrater reliability was computed using both Intraclass Correlation (.870) and a score agreement (93.6%) procedure. Internal consistency (using Cronbach’s Alpha) was .895. Test-retest reliability (score agreement) was 100%. Taken together, these results demonstrate that the rubric is robust when used to analyze experienced teachers’ descriptions of lessons or projects offered in response to the interview questions that appear in the Appendix.
