This is a description of part of the CTOPP that we have from one of my children's evals by a reading specialist:
Phonological awareness – (assessment tasks include elision, or saying and changing words by dropping sounds, and blending sounds to create new words)
Children with well-developed phonological awareness learn to read more easily than do children with poorly developed phonological awareness. Scores below 90 indicate a deficit.
Elision example: Say tan. Now say tan without saying /t/
Blending Words example: Put the parts together: s-o = so
The test that was included in CTOPP that looked closest to nonsense words was "Nonword Repetion"- example: Repeat each word exactly as you hear it: wudoip
Our dd's test included DIBELS which has a section on nonsense words - she also had several other reading tests, if you want I can look through her report at the others. The person who did her eval did a really good job of explaining the tests and testing objectives as they related to reading skills.

What other tests did your ds have?
