How do you evaluate the reliability and validity of an early literacy assessment?

• A. Check consistency across administrations (reliability) and whether it measures the intended construct (validity), including content and construct validity.
• B. Only measure speed of completion.
• C. Compare to non-educational benchmarks.
• D. Use a single administration and assume validity.

Answer: (A)

To evaluate an early literacy assessment, you need evidence that it is reliable and valid. Reliability means the scores you get are stable and consistent across different situations and people. Check how scores hold up across administrations (test-retest) to see stability over time, how consistently different scorers rate the same responses (inter-rater reliability), and how well the items hang together to measure a common skill area (internal consistency). Validity asks whether the test actually measures what it intends to measure. Content validity looks at whether the items represent the key early literacy skills we expect to assess—phonemic awareness, letter knowledge, print concepts, decoding, and early comprehension. Construct validity involves showing the test aligns with the broader literacy construct so scores move with other established literacy measures (convergent validity) and don’t align with unrelated abilities (discriminant validity). If possible, criterion-related validity shows the test’s scores predict future reading achievement or correlate appropriately with other criterion measures. Context helps here: use the tool as part of a broader data picture, not in isolation. Train scorers, pilot items, and compare results with standards or benchmarks to ensure the assessment supports instruction and progress monitoring. Choosing an assessment based on a single administration or on speed alone, or comparing it to non-educational benchmarks, won’t provide meaningful evidence of reliability or validity.
