Advice for Coassessing in the Virtual Environment

What is Coassessing?

Coassessing is when coteachers:

  • Analyze the results of student assessment to determine next steps for instruction AND/OR

  • Reflect on lesson implementation

Regardless of whether coeachers are reflecting on the results of student assessments or lesson implementation, the goal of coassessing is to allow data to inform instruction and increase K-12 student learning.

Assessments might be formative (e.g., quickwrites, homework, exit slips) or summative (e.g., lab reports, tests, essays). In either case, coassessing conversations should focus on what students have learned, where there is room for growth, and next steps for instruction.

Coassessing Tool: How to Use It

The coassessing tool was developed to provide indicators of what coassessing looks like when done well and leads to the professional growth of BOTH teachers.

In the following video, faculty from CSU Stanislaus provide an overview of the coassessing tool and the key indicators to think about when collaborating with your coteacher on data-driven instruction. Even though this video was created in April of 2019, the faculty modeling the coassessing approach did so virtually. Please note: The coassessing tool has been updated as of August 2020, so the tool linked to above is slightly different than the tool featured in the video.
