I send this questionnaire home to parents every year. It is always so well received and sets a tone for parents that you care about their child as an individual. It also gives you something to refer to for EACH pupil, building those positive relationships from day 1.
FYI: This year, I will send the questionnaire home with kids and parents will upload their answers to Seesaw. You could also ask parents to send it to a school email.
The file in in doc format so editable to your needs. The questionnaire features 11 questions.
