This is an Initial /R/ probe check for words, phrases, and sentences. As a SLP on the Go, I found that sometimes I need a quick check of skills and additional data support. This skills check is used for Response to Intervention (RTI) probing over a baseline data (pre-test) and post test data. This probe check has proven quick and easy as a supplement to probe skill level for an intake meeting and its documentation. Data sheets are included for both 4 week and 6 week probing. A Student on the go practice sheet is included for student to take home or to the classroom for practice.
