Nigeria is one of the countries that can, from 1st February 2023, apply to be a recognised UK teacher under the Qualified Teacher Status (QTS) framework introduced by the Department of Education (DfE).
In order to be considered, you must have all the requirements the DfE is asking of you. The eligibility are detailed here and on the DfE government website here.
Based on research, to be recognised as a teacher in Nigeria, you will need the minimum of the Nigeria Certificate in Education (NCE) and a TRCN license according to superprof.ng.
The NCE is what is required to teach primary and junior secondary school students. Once this is acquired, individuals can take the TCRN’s Professional Qualifying Examination (PQE).
If the exam is passed, a registration can then be done to gain the official teaching license given by the Teachers Registration Council of Nigeria (TRCN).

To teach higher schools, for example senior secondary schools, you are expected to have at least completed a bachelor’s degree.
And if the desire is to teach at a much higher level like a university, a Post-Graduate Diploma in Education (PGDE) is required.
The UK is currently requesting Nigerian teachers and others have experience in teaching 11 – 16 year old secondary school children, hence the requirement one of the requirement being a Bachelor’s degree.
