Figure 1 shows the distribution of the ages of the students at the time they entered Ben Bronz Academy. The bulk of the students ranged from age nine to age 16. Age 12 was both the mean and the mode. One student entered at age seven and one at age eight.
Figure 2 shows the distribution of IQ scores. The range (72 to 135) was impressively wide. The mean was 99, and the distribution was symmetrical. Thus, the distribution of intelligence of Ben Bronz students appears to be essentially similar to a "normal," unselected sample of students in the public schools. Learning disabilities seem to strike at all intelligence levels.
All of the students entered Ben Bronz Academy with the general diagnosis
of Serious Learning Disability. Many had additional, more specific, co-occurring
diagnoses. These diagnoses and their frequencies of occurrence are shown
in Table I. (Since each student may have had more than one diagnosis, the
frequencies are not totaled.) Attention Deficit Disorder, Language Disorder
and Dyslexia were the most frequent co-occurring diagnoses.
