How the formative assessment tool works

Decide which skills to assess

You can assess specific reading, math, and early literacy skills using pre-made items and tests aligned to state standards, or test skills in any subject area—including social studies, science, and more—when you author your own test items.

Select and assign skill checks

Once you select (or create) a skill check, it’s easy to assign it to individual students, student groups, or an entire class, so you can check understanding of specific skills. Watch this short video to see the process in action.

Track student progress

Reports and dashboards help you determine which skills students know, how deeply those skills are understood, and where to differentiate instruction.

Multiple-choice items

Star Custom offers two item formats: multiple-choice and constructed response. Automatic scoring and immediate feedback for multiple-choice items help students take ownership of their own learning.

Constructed-response items

Star Custom offers two item formats: multiple-choice and constructed response. Constructed-response items allow students to demonstrate deeper knowledge and understanding of a concept. Rubrics in the software help teachers to score constructed-response items.
