Which assessment should I choose?
Comprehensive covers 11 executive function skill areas in 77 questions. Foundational covers 5 core areas in 30 questions, with simpler wording.
The two side by side
- Comprehensive: 11 skill areas, 77 questions, about 30 to 40 minutes
- Foundational: 5 skill areas, 30 questions, about 15 to 20 minutes
How they differ
Foundational is not a shortened Comprehensive. It asks about core building-block skills, in simpler wording, so it tends to suit younger learners and anyone who finds a long form hard to finish. It is often the better fit for a person with higher support needs.
Comprehensive gives you the fuller picture and skews older: later elementary, teens and adults, when the longer format feels manageable.
If you cannot decide
Start with Foundational. A finished Foundational assessment tells you more than a Comprehensive one somebody abandoned at question 40, and you can run the other one later.
Age is a rough guide here, not a rule. A tired teen at the end of a school day may do better with the shorter form than a focused nine-year-old.
