OWLS HELP!

I’m an elementary SLP, and I use the OWLS (among other assessments + informal measures) for language evaluations. I know assessment selection depends on the student, the concern, etc., but my school psychologist is making me redo a whole assessment because they claim the OWLS is “like a screener.” I’ve always understood the OWLS to be a comprehensive language assessment that evaluates listening comprehension, oral expression, and written language. While I know it doesn’t give a full breakdown like the CELF in all areas, I’ve found it useful for assessing language skills in depth. Can someone educate me on whether the OWLS is considered appropriate for language assessments, and in which cases it is (or isn’t) the best tool? I’d love to hear your experiences, especially if you’ve had similar pushback from psychs!

Edit: Thank you! She said it is not an assessment that is defendable in court or to make any eligibility/exiting of any student?
