Early reading performance: a comparison of teacher-based and test-based assessments

Area of Science:

• Educational Psychology
• Developmental Psychology
• Learning Disabilities

Background:

• Early identification of children at risk of educational failure is crucial.
• Existing teacher assessments often lack predictive validity for reading difficulties.
• Teachers may not accurately identify the majority of students with severe reading disabilities.

Purpose of the Study:

• To compare the effectiveness of test-based versus teacher-based assessments for identifying at-risk students.
• To evaluate three newly developed educational screening instruments.
• To determine the concurrent validity of teacher ratings and standardized tests in early reading assessment.

Main Methods:

• Developed three screening instruments: a teacher rating scale, a teacher questionnaire, and a battery of language/reading tests.
• Assessed the concurrent validity of these instruments in 312 Australian schoolchildren (Kindergarten to Year 2).
• Students were assessed at the end of the school year, having completed 1-3 years of schooling.

Main Results:

• The skills required for reading success evolve during the first three years of schooling.
• Agreement between teacher assessments and test results increases with grade level.
• Teacher rating scales demonstrated potential as a cost-effective screening tool.

Conclusions:

• Teacher rating scales, when carefully focused, can be valuable for early identification of reading risk.
• Further development and implementation of improved teacher rating scales are recommended for early screening.
• The alignment between teacher and test assessments grows as reading becomes more measurable in later elementary years.
