How this list was compiled: Outline: Stanford Achievement Test Series, Tenth Edition, Scope & Sequence chart (Pearson), https://www.pearsonassessments.com/content/dam/school/global/clinical/us/assets/sat10/sat10-scope-sequence.pdf, linked from the publisher's product page, https://www.pearsonassessments.com/en-us/Store/Professional-Assessments/Academic-Learning/Stanford-Achievement-Test-Series-%7C-Tenth-Edition/p/100000415, both read 2026-10-10. The product page says the Science subtest assesses the life, physical and earth sciences and the nature of science, and that the Social Science subtest measures concepts important for the development of citizenship. Each fact was read on the public page named on its question (NOAA, NASA Space Place, U.S. Geological Survey, U.S. Energy Information Administration, National Archives, USA.gov, Wiktionary), all 2026-10-10. Licence: Own work. Every question, passage, answer choice and explanation was written for this page. None is taken or reworded from a Stanford test, from the publisher's subtest examples or practice tests, or from another practice test.

Why the practice sits at Intermediate 1

The Stanford 10 has 13 levels, and Intermediate 1 has the longest complete battery on Pearson's chart: 402 questions. It is also the last level with Word Study Skills, so this set practices every subtest the chart lists for grades 3.5 to 9.9 except Listening.

What the questions are built from

Each subtest's share of the 72 questions follows the chart's question counts. Mathematics and language questions name a Common Core standard, and every mathematics answer is worked out a second time. Science and social science facts were read on public pages, most of them federal (NASA, NOAA, the U.S. Geological Survey, the National Archives), each linked under its question.

Questions and answers

What is on the Stanford Achievement Test?

Reading, mathematics, language, spelling, listening, science and social science, in up to ten multiple-choice subtests that change with the level. Below grade 3.5 the chart lists Environment in place of Science and Social Science.

How long is the Stanford Achievement Test?

Pearson's chart plans 2 hours 15 minutes for the first kindergarten level and up to 5 hours 30 minutes at Primary 3 and Intermediate 1, for the complete battery. The test is untimed: the chart calls its times guidelines.

What grades take the Stanford Achievement Test?

Kindergarten to grade 12, in 13 levels: SESAT 1 and 2, Primary 1 to 3, Intermediate 1 to 3, Advanced 1 and 2, and TASK 1 to 3 for grades 9 to 12. The box under the questions gives each level's grades and subtests.

How is the Stanford Achievement Test scored?

Pearson's page names no pass mark. It lists percentile rank, stanine, grade equivalent and normal curve equivalent by grade, plus scaled scores, against national norms. A score on this page cannot be turned into any of them.

Can homeschoolers take the Stanford Achievement Test?

Yes, through a reseller. Pearson's product page says it will not sell tests to home school students, or score or report their testing, and it lists the home school resellers to contact instead.
