That helps. The CELF-5 does have optional reading and writing portions, although they typically are not given in a situation where a comprehensive achievement instrument has already been administered. The primary interest in administering both oral and written language measures is to compare receptive and expressive language in the oral and the written contexts. E.g., listening comprehension vs reading comprehension, and oral expression vs written expression. However, the lowest scorable age range is nine for reading and writing, so these would have to be for clinical information only. If she gave the entire CELF-5, with all of its optional subtests, and he needed many items to reach a natural ceiling, then three hours becomes a more realistic estimate (still a little high, but reasonable with the noted breaks). Another possibility is that she gave a different measure of reading (for the same clinical reason), such as the TORC, GORT, or GSRT. Did he have to read them out loud, or did he have the option of silent reading?
The SLP's language testing is a little more in-depth than the oral language measures from an achievement test like the KTEA-3, and can (hypothetically) be analyzed on more finely-grained clinical dimensions, which would be why additional eval in language might take place.
And most places I'd be just a bit shocked by the absence of an in-district psych, but where you live, they are constantly advertising job openings, and often have positions that consist of coverage for a region a hundred miles across. I know people who've tried conducting evals by Skype/FaceTime...
