Timothy's Scaled Scores to date

Subtests are grouped by the Index Scale in which they fall (pg 4 of manual)
Raw scale is listed, then scaled score:

Verbal Comprehension Index Scale
Vocab: 53, 18
Similarities: 26, 11

Perceptual Reasoning Index
Picture Completion: 19, 14
Cancellation: 12

Working Memory Index
Digit Span: 32, 12
Letter-Number: 19, 9

Processing Speed Index
Coding: 78, 11
Symbol Search: 44, 14
Cancellation: 47, 12





A reminder about scaled scores: they are standardized units that are equal in value; meaning a scaled score of 9 on Block Design represents the same level of ability as a scaled score of 9 on Vocabulary. Scaled scores are directly related to Standard scores, which is the type of score given in a FSIQ or other Index score, meaning that a 10 is considered average like an IQ of 100 is considered average. While 'Average' is used as a reference point for scores on either side, please remember to consider the context of an individual's scores. Just because Timothy's scores are almost all 'Above Average,' there is more to say than that.

We will be talking more about interpretation and conceptualization in the next weeks, but I want you to start thinking about the picture you are getting.
