My son took the WPPSI when he was 5.5. As I recall there were three subtests. He scored 19 out of 20, 16 out of 20 and 9 out of 20.
The test he did poorly on was a "coding" test that required the use of a pencil. A 9 out of 20 was considered equivilent to an IQ of 107, and this section pulled his score down to 128 or 129. An "alternate" test was given, and he scored 14 out of 20 on this test, but it was not used to compute his score.
My point is, if your daughter had to use a pencil for part of the test, this would likely pull her score down given her young age.
