What does Gc represent
Comprehension Knowledge
What is the total number of subtests in the WJ Cog
18
Can you stray from general administration procedures?
No, it is best to administer according to standardization practices....
However, if for some reason you must, you should document it in your report and interpret results with caution
What does Letter Pattern Matching measure?
Gs-P Perceptual Speed
What are confidence intervals?
Increases “confidence” that the examinee’s true score falls within an identified range, but does not increase precision of obtained score.
Uses the standard error of measure (SEM) around the obtained standard score to create the range.
Commonly available confidence levels are: 68%, 80%, 90%, and 95%. The higher the confidence level, the wider the band.
What is Gf
Fluid Reasoning
How many subtests do you need to administer for the standard battery?
1-10
Can you penalize for mispronunciations due to speech difficulties, regional or dialect differences
No
What does phonological processing measure?
Ga-PC (Phonetic Coding)
Glr-LA (Speed of Lexical Access)
Glr-FW (Word Fluency)
What are standard scores?
Describes performance relative to the average performance of the comparison group.
Example: M=100, SD=15
What is Ga

What does story recall measure?
Glr-MM (Meaningful Memory)
What are percentile ranks?
Describes performance as relative standing in the comparison group on a scale of 1 to 99.
Indicates the percentage of comparison group who had scores the same as or lower.
What is Gs

When do you choose age norms versus grade norms?
Generally grade norms are preferable in school-based settings; age norms in ungraded settings
