They have low validity and reliability.
Step-by-step explanation:
Critics of projective tests argue that they lack validity and reliability for they often rely on subjective scores. The scores that projective tests give a lack of objective measures and cannot account for a reliable result.

The projective tools uncover quickly feelings, and desires or conflicts that can be worked through therapy, and often they have limited use for they apply very uniquely to a particular needs.
