Fifty-six teachers of students with moderate/profound disabilities viewed task analytic data in one of three forms: graphed, ungraphed, or both. The data's form did not produce different teacher judgments of student progress or different program recommendations. Three factors (trend, variability, and frequency of data collection) had significant main effects on judgments. (Author/JDD)
