What feedback should we expect to receive from senior schools about how candidates performed in CE exams?

Senior schools are asked to report candidates' results to prep schools using grades. They are also asked to adhere strictly to the results deadline given in the information for schools about the administration for both CE at 11+ and 13+. Prep schools find it extremely helpful to receive as much information as possible about how their pupils performed in the examinations. Heads of Department welcome written reports or verbal feedback from their senior school colleagues.
