Abstract
This research aims to determine the 4C skills of Padang City High School students. The research design uses the R & D method and the ADDIE development model, which includes five development stages, namely analysis, design (develop), implementation (implement) and evaluation (evaluate). The research instruments used were validation sheets, communication and collaboration skills questionnaires and critical thinking and creative thinking skills test sheets. From the results of initial research at three schools in Padang City, it was found that critical thinking skills (45.65%), creative thinking skills (40.46%), communication skills (61.77%) and collaboration skills (61.46%). This shows that students' 4C skills are still lacking. To overcome this, researchers proposed a solution by developing a PjBL model physics learning assessment instrument to improve 4C skillsĀ learners
