A Teaching Career on One Channel

I spend most of my working life removing single points of failure from school systems. One person who knows how the bursary reconciles. One phone that holds the parent database. One teacher who is the only one who can cover further maths. The pattern is always the same, and so is the fix: the system is not fragile because any part is weak, it is fragile because there is only one of that part.

Teachers run their careers this way almost universally, and nobody points at it. One full-time job, in one city, obtained through one person who knew someone. It works until it does not, and when it fails it fails completely: a school closes, a salary goes three months late, a proprietor changes, and an entire household income stops at once.

The channels that exist

What follows is not a hustle list. It is an inventory of the ways teaching qualifications already convert into income in Nigeria, roughly ordered by how quickly a teacher can switch each one on.

• Part-time and specialist periods. Schools increasingly build timetables around people who come two or three days a week — IGCSE sciences, French, music, ICT, phonics. A free afternoon or a day off can carry another school’s periods. For someone between jobs, three part-time arrangements can out-earn one full-time salary, and they fail independently of each other, which is the entire point.
• Examination work. Marking, invigilation, and coordination are seasonal, predictable, and pay for expertise you already hold. They also put you in a room with people who hire.
• Home lessons and small-group tutoring. The oldest channel, and the one most often run badly — no written rate, no schedule, no record, payment when the parent remembers. Run it like a service with terms and it becomes reliable income rather than a favour that pays sometimes.
• Structured content. Scheme-of-work materials, worked past-question sets, revision packs. This is slow to start and the only channel that keeps earning while you sleep.
• Training other teachers. If you have a genuine specialism — a curriculum, an exam board, a subject other teachers fear — schools pay for the transfer of it. This channel also compounds your reputation faster than classroom work, because it is performed in front of adults who talk.
• Institutional and edtech work. Curriculum design, assessment writing, product work for the companies building school software. Underexplored, and the people who do it are usually just the teachers who made themselves visible and reachable.

What every channel actually requires

The requirements barely differ from the ones that get a teacher hired in the first place, which is the useful part: the same small pieces of infrastructure serve all six.

A statement of exactly what you offer and when you are available. A phone number that is answered. A record of results you can show. One document that survives a WhatsApp forward. A reputation held by three or four people who will say something specific about you when asked. Build those once and every channel above becomes a matter of pointing them somewhere new.

The failure mode to avoid

I am not arguing for spreading yourself so thin that the primary job suffers — that is the version of this advice that ends badly, and schools are right to resent it. A second channel that makes you late to your first is not diversification, it is decay.

The discipline is the same one I would apply to any system carrying real load: add the second channel only when you can meet its obligations without degrading the first, write the terms down before starting, and let each one stand on its own record. Two arrangements honoured properly beat five entered casually, in income and in reputation, and reputation is the asset that actually compounds here.

Why this is a systems argument, not a money one

The reason I care is not that teachers should earn more, though they should. It is that a teacher on one channel has no leverage, and a professional without leverage cannot insist on anything — not on being paid on time, not on class sizes, not on being treated as a specialist rather than an interchangeable body. Every school failure I have ever been called in to fix was made worse by staff who could not afford to push back.

A second channel is not primarily extra income. It is the ability to say no. That single capability changes the terms of every conversation a teacher has with a school, and it is the cheapest structural upgrade available to anyone in the profession.
