This is the pdf version of the form I leave in my student's folder to share what we have worked on during our sessions with their family. I generally make double sided copies so that I can get 8 weeks to a sheet. Each block allows you to check of the day(s) of the week that a student was seen.
It is very simple and indicates what general skills we worked on (articulation, social skills, language, fluency) and a section for 'other' with a space for a brief description. There is also a comment section for both SLP and parents that way I can write down percentages or a quick note and they can jot a question or let me know any important updates. I also include a line to indicate whether or not home practice has been assigned, that way there is no question about it!
I have found this form to be a good balance between giving parents some info about our sessions and not needing to spend oodles of time writing notes. I try to explain to parents at our initial IEP meetings that I can either spend time writing a novel about the session or actually having a session (and I prefer the later). I hope this helps make your sessions more efficient!
