What Star Math measures
Star Math measures K–12 students’ overall math achievement and growth in core math domains, including Numbers and Operations, Algebra, Geometry and Measurement, Data Analysis, Statistics, and Probability. These assessments evaluate computational skills, conceptual understanding, and problem-solving abilities to guide instruction and track growth.
Numbers and operations
Star Math measures students’ ability to add, subtract, multiply, and divide whole numbers, fractions, and decimals. This domain also covers primes, square roots, percents, and numerical expressions.
Algebra
Students are asked to graph points and functions, evaluate variables, solve linear and nonlinear equations, simplify expressions, and complete other key algebraic tasks.
Geometry and measurement
Star Math measures students’ ability to identify shapes, lines, and angles; determine and convert measurements; tell time; calculate the perimeter, area, volume, and surface area of shapes; and determine missing measurements or dimensions.
Data analysis, statistics, and probability
Students are asked to read and answer questions about charts, tables, and graphs; calculate mean and median; make estimates and determine probabilities; and visually represent data sets.
How Star Math fits into the Renaissance Star ecosystem
Star’s computer-adaptive math tests—Star Math and Star Matemáticas—can be used alongside Star CBM Math to efficiently provide educators with a more complete view of student math performance. Together, these complementary assessments combine broad measures of overall math achievement with deeper insights into students’ math achievement and learning progress. When used together, Star Math and Star CBM Math help educators better understand what students know and where they may need additional support. Star Math and Star Matemáticas help determine whether language is a barrier to math performance or if learning gaps are skill-based—without over-testing students.
Star Math assessments also help inform purposeful math instruction and practice. Educators can use results to support learning through Renaissance solutions such as Freckle, as well as core curriculum. Together, assessment and practice help reinforce mathematical understanding, personalize learning, and support math growth within a coherent instructional experience.
Star Math is available in Spanish
Star Matemáticas provides Spanish‑language math assessment that honors students’ linguistic strengths while delivering the same trusted insights as Star Math. With equivalent rigor and reporting, educators can confidently assess achievement and growth for Spanish‑speaking students—and make informed instructional decisions without language acting as a barrier.
