We have amazon tablets ..all are password protected with a simple formula for the whole group so that we can share if we need to (we do all have our own) Then its just a quick 4 digit code to get into the app . I have set my tablet to shut off after a longer time than my staff as i always seem to get distracted! Not all obs will have a photo (in fact this has been a discussion this term about not needing to photograph all the time) Instead of doing a paper tracker i print a pdf of the group assessments so that they can see if they are missing anything. We do next steps every fortnight and these are on the system to so that parents can get involved.
