The third Carry On film, following on immediately from the successes of Carry On Sergeant (1958) and Carry On Nurse (1958), the series was starting to gain momentum, and for the third film, producer Peter Rogers, writer Norman Hudis and director Gerald Thomas decided to lampoon the formalities of the education system. It's a good little comedy, but still innocent compared to what was to come. Set at Maudlin Street Secondary Modern School, the headmaster William Wakefield (Ted Ray) has been there for 20 years, but he has seen an advert looking for a head of a brand new school which he applies for. But first, he has to oversee a Ministry of Education Inspector Felicity Wheeler (Rosalind Knight) and child psychologist Alistair Grigg (Leslie Phillips). Wakefield tells the teachers, including English teacher Edwin Milton (Kenneth Williams), music teacher Michael Bean (Charles Hawtrey), Maths teacher Grace Short (Hattie Jacques) and P.E. teacher Sarah Allcock (Joan Sims) of his plans to leave, but the pupils have other ideas. It's a very silly film, but it's a Carry On film with a heart, even though this is a school where the antics of the pupils would make the pupils of St. Trinians look like saints, they're doing it because they don't like change. There are some funny pranks and antics, and it's a joy to see the regulars having fun and being good sports.
