I use this data sheet to take data during my speech therapy sessions. You can cut the page in half (less paper in all those data binders!) or take data on two kids at once or one student across two sessions. I circle the sound(s) I'm listening for and what level the student is working at. There is a spot to mark if the student is hearing a model and if you or an app on the iPad is giving the model. There is also a space to jot down sounds you hear correct and incorrect during your conversations during the therapy session for extra information on the generalization of sounds not being worked on during that session.
