What the test measures

Number and Operations in Base Ten skills

  1. Recognize that in a multi-digit number, a digit in one place represents 10 times as much as in the place to its right and 1/10 of what it represents in the place to its left

  2. Explain patterns in the number of zeros of the product when multiplying a number by powers of 10

  3. Read, write, and compare decimals to thousandths

  4. Use place value understanding to round decimals

  5. Fluently multiply multi-digit whole numbers using the standard algorithm

  6. Find whole-number quotients of whole numbers with up to four-digit dividends and two-digit divisors

  7. Add, subtract, multiply, and divide decimals to hundredths in real-world problems

Standards basis

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).
