Grades 3–5: What Kids Learn and What CAASPP Tests
What California 3rd, 4th and 5th graders learn in math and English, how CAASPP testing works, and the 5th-grade math placement that decides 6th-grade math.
Math in grades 3–5
Fractions arrive in 3rd grade as a new domain, Number and Operations—Fractions, and stay through 5th (California math standards). Alongside them come multiplication and division, multi-digit arithmetic, decimals, and area and volume. The guide to fractions in grades 3–5 explains where students get stuck.
English in grades 3–5
Phonics and fluency standards continue through 5th grade, while reading shifts toward literature and informational texts that students explain and compare (California English standards). In writing, opinion pieces need reasons, informative pieces get organized into paragraphs, and narratives get a clear sequence.
CAASPP testing starts in 3rd grade
Students in grades 3 through 8 take the Smarter Balanced tests in English language arts and math each spring. 5th graders also take the California Science Test (CAST) (CVUSD). CVUSD's testing window "begins in March and concludes the last day of school." Results sort students into four levels, which reports for the spring 2026 tests call Advanced, Proficient, Developing and Minimal; earlier reports said Standard Exceeded, Met, Nearly Met and Not Met (CDE, score ranges, 2025–26 edition).
The score report guide explains the levels. The Conejo Valley test scores page shows how 31 local schools did.
5th grade and middle school math placement
5th-grade math decides where a student starts in middle school, and each district does it differently:
- CVUSD: 6th graders are placed in Math 6CP, Math 6 Honors or Math 7 Honors. 6 Honors uses 5th-grade grades, the 5th-grade End-of-Course exam and the SBAC math score. 7 Honors is open only through the June Challenge Exam, with 83% or better in 2026 (CVUSD 2026 letter). See the CVUSD placement guide.
- Las Virgenes: a placement test at the end of 5th grade, plus teacher referrals, sets Math 6, Math 6 High or Math 6 Accelerated (LVUSD). See the Las Virgenes guide.
- Oak Park: every 6th grader at Medea Creek takes Math 6; acceleration decisions come in 6th and 7th grade (OPUSD policy). See the Oak Park Algebra I guide.
Thousand Acorns Tutoring does not offer placement exam prep. These are the districts' published rules.
