We evaluated the psychometric properties of the Trauma Informed Practice Scales -- School Counseling Programs Version scores using item response theory with a sample of 270 school counselors. Participants ranged in age from 24 to 69 years (M = 42.82, SD = 9.96). Participants identified as female (81.5%), male (14.1%) or unreported (4.4%,). Participants' racial and ethnic backgrounds were: White (79.3%), African American or Black (5.6%), Multiracial (5.2%), Latino/Hispanic/Spanish (4.8%), American Indian/Alaskan Native (0.4%), Other (0.4%), or unreported (4.4%). Participants from 14 states completed an online survey, which included demographics questions and the TIPS-SCP. After removing the poorly performing items, partial credit model estimates explained 58.63% of the variance in participant responses. We found psychometric evidence to support its ability to capture trauma informed practices in schools and school counseling programs.
