How to interpret a Dimensions placement test
The publisher says the Dimensions Math A/B placement tests measure mastery of the named book. These are not ordinary scored school examinations: the publisher recommends not timing placement tests, allowing at least one hour, and using mistakes and strategies to diagnose skill gaps. The tests sample representative skills rather than every topic in the curriculum.
These instructions do not prevent a particular school from having different policies, but a short timed result should not be treated as identical evidence to an untimed diagnostic.
