learning function diagnosis, it is generally accepted that a standard
score of –1 or lower indicates poor functioning and standard score of
–2 or lower indicates a very low level of functioning. It is important
to note that the Israeli education system differentiates between the
cutoff point for providing treatment and the cutoff point for granting
accommodations in testing method. Therefore, the presentation
of the findings refers to two levels of functions: one, a low level of
functioning (standard score of –1 to –1.99), and the other, a very low
level of functioning (standard score of –2 and lower). Such reference
to a standard deviation from the average and so forth is common in
intelligence tests for adults, such as WAIS-R [9].
