During the [name blinded for manuscript review] project summer professional development, the Integrated CT Assessment was piloted with 72 elementary teachers. The assessment is based on computa- tional thinking integration literature and asks teachers to identify different computational thinking concepts in content area scenar- ios. The assessment allowed us to identify which computational thinking concepts teachers were most familiar with prior to the professional development and assess changes in their understand- ing following the professional development. Our next step will be validation of the assessment with a larger group of teachers.
