Below that are links to free Singapore Math placement tests for K-6 for its U.S. editions, and its Standards Edition.
Which placement test should you use?
My preference is to use the Singapore Math placements tests for K-3.
But I prefer the Saxon Math placement tests for Grades 4 to 12.
Saxon Math placement tests:
- Primary Grades (Math K-3) placement test
- Middle Grades (Math 54 through Algebra 1/2) placement test
- Algebra 1 placement test
- Algebra 2 placement test
- Upper Grades placement test
Singapore Math placement tests
This link will take you to all of the Singapore Math placement tests. (If this link changes, please let me know, and I'll find you another.)
Caution: Singapore Math now has a discovery series they say is aligned with the Common Core State Standards; my recommendation is to avoid the Discovering Math series from Singapore Math.
I've used the U.S. Editions and the Standards Edition of Singapore Math to tutor, and I found them word-heavy, but otherwise pretty solid.
