Well that didn't apply in my case. In 1980 I was still a Catholic, though on the drift. Four years earlier I'd got married in a Catholic church and I was already teaching in a Catholic school in east London when I applied. In 1973-74 I'd even taught a few lessons in religious education. I didn't see why a science teacher needed to do the Catholic Teaching Certificate. It wasn't a condition of employment. I was fully qualified and experienced for the job I was applying for.
