What the test measures

Number and Operations—Fractions skills

  1. Explain why a fraction a/b is equivalent to a fraction (n×a)/(n×b) using visual fraction models

  2. Compare two fractions with different numerators and different denominators by creating common denominators or numerators

  3. Add and subtract fractions with like denominators and solve word problems involving fractions

  4. Decompose a fraction into a sum of fractions with the same denominator

  5. Add and subtract mixed numbers with like denominators

  6. Solve word problems involving addition and subtraction of fractions referring to the same whole and having like denominators

  7. Understand decimal notation for fractions, and compare decimals to hundredths

  8. Use decimal notation for fractions with denominators 10 or 100

  9. Compare two decimals to hundredths by reasoning about their size

Kentucky Academic Standards (KAS) for Mathematics — Kentucky

How the KSA reports it

Kentucky KSA is a state summative assessment built on Kentucky Academic Standards (KAS) rather than a separate national framework. For mathematics, the assessed content closely follows Common Core–style grade-band domains in grades 3-8 and uses Kentucky high-school conceptual categories in grade 10.

Blueprint & weighting

KSA uses the Independent / state-specific framework (by grade domains structure).
