validity: Validity might not hold because, each student might be in a different grade level

stability: Stability might not hold because, each students information might be taken at a different time –Teaching method in schools are very different nowadays– and age

representativeness: Might be a data of a specific state or place

Unconfoundedness: If they took a test earlier to see what class type they were.
