A September intake is decided in January.

Agencies talk about intakes as if they were seasons that arrive. They are not. A September intake is a project with a fixed end date and a known critical path, and the only real variable is whether you planned it backwards from the first day of teaching or forwards from whenever enquiries happened to arrive.

The backward pass below is written for a northern-hemisphere September start. Shift it for a January or a February intake; the structure does not change.

September: the fixed point.

Teaching starts. Students must be in the country, enrolled and housed. Work back from this date, not from an application deadline, because arrival is what the family cares about and it is the only date that cannot move.

August: arrival and the last mile.

Flights, accommodation confirmed, arrival connectivity sorted, pre-departure briefing delivered, emergency contacts exchanged. Nothing in August should be a surprise. If a visa decision is still outstanding in August, the file was late in April.

June to July: visa decisions.

This is the crunch, and it is where capacity fails. Interview slots and appointment availability are outside your control and they are worst at exactly this moment. Every week you pull a file earlier than this window is a week of risk removed. Book what can be booked as soon as it can be booked.

April to June: applications and offers.

Applications submitted, conditions cleared, deposits paid, enrolment confirmations issued. Two things determine whether this phase is calm: whether documents were collected in the spring, and whether conditional offers had a named owner chasing them. A conditional offer with no owner sits until someone notices in July.

February to April: shortlisting and documents.

The single highest-leverage phase, and the one agencies compress. Shortlists agreed with families, test results obtained or scheduled, transcripts requested from institutions, passports checked for validity and renewed where needed, funds discussed honestly and started seasoning where a destination requires it.

January: counselling and capacity.

Enquiries converted to counselling sessions, destinations and budgets discussed frankly, fee schedules given in writing, and — the part that gets skipped — your own capacity planned.

Count how many active files each counsellor can carry through the June crunch without dropping any. Multiply. That is your intake ceiling. Recruiting past it does not produce more enrolments; it produces the same number of enrolments and a larger number of complaints. If the ceiling is lower than your target, the decision in January is to hire, to narrow the destination mix, or to accept a smaller intake — not to hope.

Three things worth measuring while it runs.

• Days from enquiry to first counselling session. This is the number that quietly determines conversion, and it is the easiest to fix.
• Files stalled more than fourteen days with no dated next step. Not slow files — stalled ones. The distinction is the whole point.
• Documents outstanding per file, by week. It should fall steadily from March. If it is flat in May, the intake is already in trouble and nobody has said so yet.

Plan the holidays before they surprise you.

Institutions close, embassies close, and so does your own office. Lay the destination's holiday calendar, your local one, and your team's leave over the schedule in January, and you will find the two or three weeks where a step you assumed would take five days will take three. Move those steps earlier rather than discovering the closure on the day. This is the least interesting paragraph in this article and it prevents more August emergencies than any other.

Running two intakes at once.

By April you are also counselling for January. Two intakes overlap in every calendar, and the later one always loses, because the nearer deadline shouts louder. Protect it explicitly: a fixed share of counselling time each week that belongs to the next intake and cannot be borrowed, held by a named person rather than by good intentions. Otherwise January is planned in November, and November is too late for exactly the same reasons September was.
