The answer is almost certainly 'No'.
I was in secondary teaching from 1975 to 1990. When I first started, old pupil records could stay in the files for years. (They'd eventually be destroyed, simply to create some space). By the time I left, 'data protection concerns' were at the forefront of everyone's minds and it was a strict rule that all records (except, of course, for such things as achievements in public examinations) had to be shredded within 24 hours of a pupil leaving the school.

PS: Even if you could read what was on the files, you'd probably find that there was very little there. Apart from 'routine' information (such as telephone numbers to contact your parents in the event of an emergency), you might find something like the following:
Age 6: John's mother wrote to state that John was upset because boys and girls had to get changed together for PE.
Age 9: John's mother phoned to say that she was concerned that the stress of going on the school camping trip might lead to a recurrence of his bed-wetting problems.
Age 13: The head teacher reprimanded John after he bought items from fellow pupils while knowing that they'd been stolen them from a local shop.
Age 15: The employer who had accepted John for work experience wrote to state that John is a credit to his school and it was a pleasure to have him working for the firm.
That might not seem much for 11 years but I've seen hundreds of school records and most files contained even less than the content of my example.
