Formative assessment tool for K–12

Guide every student to mastery

With Star Custom, you can support a cycle of informed instruction using quality skill checks aligned to your state standards. You’ll get greater insight into the skills students have mastered and those that need more work—so you better target instruction and move learning forward.


Teachers can choose pre-built tests, select from thousands of pre-made items, or create their own items to design the perfect formative assessment.


Pre-made items for reading, math, and early literacy assess specific skills and state standards. Reports show exactly where students excel or struggle.


Data from multiple Star Assessments—including Star Custom—combine to provide a complete picture of students’ understanding and mastery of concepts.


Star Custom provides thousands of high-quality items for language arts, math, and science. Teachers can create items for social studies, health, and more!

From standard to skill to subskill

Get a complete picture of student mastery with easy-to-read reports—so you can make instructional decisions with confidence and improve day-to-day learning gains.

The Renaissance Mastery Dashboard shows how close students are to mastery and indicates whether additional assessments may be helpful

The Item Responses Report shows how students responded to each item, so teachers can more easily pinpoint exactly where students may struggle.


Transform formative assessment into actionable insight

Unified measure of mastery

Only Renaissance integrates data from multiple Star assessments—including Star Custom, Star Reading, Star Math, and Star Early Literacy—to provide a single, unified measure of mastery. Renaissance’s learning progressions for state then help you determine which skills to teach and track.

Intuitive reports for educators

Do you need to see results for the whole class, an instructional subgroup, or an individual student? Explore how Star Custom reports help provide data-fueled insights to help inform whole-group, small-group, and one-on-one instruction on a day-to-day basis.


Test and track mastery in 3 easy steps

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.
