PSI Is the FSIQ Valid? Yes No
If FSIQ is INVALID, is GAI Valid?
( |VCI - PRI| < 23 Points )
Sum VCI+PRI to get the GAI Sum of Scales Scores and
convert it to a Standard Score with the table below
Is the GAI Valid?

STEP 3 - SUBTEST DISCREPANCIES
Sattler still suggests comparing subtests to either the FSIQ mean, or the VCI and PRI mean to
determine a child's personal strengths and weaknesses

material; they may do well with "lecture format" classes, so
long as they do not include too many pictures, charts, and
graphs

When Gc lexical (Crystalized Lexical Knowledge) is
higher, it may indicate that the child can reason
with words, but has limited factual information;
writing may be hard because they know the words
to use, but have little to say, and can read but not
understand important points
Are These Unitary Factors? (< 5 points)
Gc lexical highest score - lowest score
Yes No
Gc general highest score - lowest score
Yes No
- = Needed - 17 Sig Non
When Gc general (General Crystalized Knowledge) is higher,
it may indicate that the child has good factual knowledge,
but difficulty with words; this may mean that on writing
assignments, the child knows what to say that does not know
how to say it, and may be able to read and understand
familiar topics but have difficulty with novel material

When Glc LTM (Long-Term Memory) is higher, it
may indicate that the child has adequate factual

topics, but when learning new material has
difficulty holding information in short-term
memory long enough to understand the "big

- = Needed - 24 Sig Non
When Gsm WM (Short-Term Memory or Working Memory) is
higher, it may indicate that the child can learn new
information, but has difficulty recalling it with a delay; others
may say they know information immediately after studying,
but forget it the next day. They likely are not forgetting, but
rather are not learning it in a way that they can later recall
