Strengths

The LSA uses photographs paired with open-ended, oral questions, which is developmentally appropriate for preschool children and allows them to express their understanding without relying on reading or writing skills.

Cautions

Because the LSA relies on open-ended, verbally administered responses, scoring can be subjective and may vary between raters.

The Life Science Assessment provides insight into children’s emerging inquiry skills and conceptual development by focusing on how they reason about real-world phenomena, rather than simply what they know. The assessment consists of structured, hands-on tasks centered on familiar physical science phenomena, specifically floating and sinking and water level. Within each task, children participate in a repeated prediction–observation–prediction cycle, where they first make a prediction, observe the outcome of an interaction with materials, and then revise their prediction based on evidence. This structure is intended to capture children’s ability to use evidence to update their thinking.
