# CORE instruments

Term I use to cover the self-report questionnaires of the CORE system ("[CORE measures](https://www.psyctc.org/psyctc/glossary2/core-measures/)") together with the CORE-A. The [CORE-A](https://www.coresystemtrust.org.uk/core-a/) is a two part practitioner completed record form consisting of the [Therapy Assessment Form (CORE-A TAF)](https://www.coresystemtrust.org.uk/home/instruments/core-a-taf-information/) and [End of Therapy (CORE-A EoT)](https://www.coresystemtrust.org.uk/home/instruments/core-end-therapy-eot-information/) form. The CORE-A has some practitioner ratings of the client's state but is not a measure, it's a suggested framework of contextualising information about the client and the therapy/intervention hence "instruments" for the CORE-A and the family of measures.
