This study investigated the psychometric qualities of 13 preschool third-party measures of social-emotional functioning. Most of the rating scales were severely limited in critical and primary areas of technical adequacy, including standardization samples, internal consistency, stability, interrater reliability, ceilings, floors, item gradients, and evidence of validity. Instruments which most frequently met the psychometric criteria were primarily recently published scales.
