KTEA-3 error analysis
What is error analysis?
Error analysis provides specific information about the relative skill proficiency of students with subtest standard scores that fall below the mean on the KTEA™-3. By investigating the errors, you can greatly enhance your understanding of a student's specific academic weaknesses and the interventions that might work well.
Error analysis also helps you:
- Describe performance on a subtest at the specific skill level relative to a norm-reference peer group
- Compare skill proficiency across subtests with similar error categories (for example, math Computation and Math Concepts & Applications)
- Develop teaching objectives and interventions
Error analysis gives you a platform for exchanging information
In today's schools, where psychologists, educational diagnosticians, special educators, and classroom teachers exchange information about students, a formal, systematic approach to error analysis using common language is helpful. Error analysis can inform effective communication about a student's academic functioning and teachers' strategies.
Carefully developed over time by experts in the field
During the development of the KTEA-3 and the previous two editions, curriculum experts in reading, mathematics, spelling, writing, and oral language helped define the specific skills measured by each subtest and the types of errors students are likely to make. Test developers also considered a review of the literature on instructional theory and practice; discussions with practicing school psychologists, educational diagnosticians, and teachers; and the actual errors made by students practicing in the data collection phases.
KTEA-3 uses two types of error classification methods
Error analysis methods are provided for 10 of the 19 KTEA-3 subtests, as shown in the table below. Within-item error analysis requires the examiner to make error classifications based on a qualitative analysis of the student's response. Item-level error analysis classifies errors automatically based on item-level scores.
