The kinds of errors that children and adolescents make on phonological processing tasks were studied with a large sample between ages 4 and 19 (N = 3,842) who were tested on the Kaufman Test of Educational Achievement-Third Edition (KTEA-3). Principal component analysis identified two phonological processing factors: Basic Phonological Awareness and Advanced Phonological Processing. Canonical analysis and correlation analysis were conducted to determine how each factor related to reading, writing, and oral language across the wide age range. Results of canonical correlation analysis indicated that the advanced error factor was more responsible for reading, writing, and oral language skills than the basic error factor. However, in the correlation analysis, both the basic and advanced factors related about equally to different aspects of achievement-including reading fluency and rapid naming-and there were few age differences.

An understanding of the strengths, weaknesses, and achievement profiles of students with giftedness and learning disabilities (G&LD) is needed to address their asynchronous development. This study examines the subtests and error factors in the Kaufman Test of Educational Achievement-Third Edition (KTEA-3) for strength and weakness patterns of students with G&LD in higher and lower level thinking skills by comparing G&LD students (n = 196) with academically gifted (GT; n = 69) and specific learning disability (SLD) students (n = 90). Several one-way MANCOVAs were conducted with subtest error factor scores as dependent variables and grouping variable (G&LD, GT, or SLD) as the independent variable. The G&LD means scores across subtests were in between the two control groups. On many higher level thinking tasks, the G&LD group scored similar to the gifted group. The results support the use of error analysis to gain further understanding into the profile of students with G&LD.
