How a language institute actually fills a batch
A language institute sells a date. The batch that starts on the fourteenth is a real thing with a room, a trainer and a fixed number of seats, and the entire counselling conversation exists to move a person into one of those seats before it starts. This makes the sales cycle short, deadline-driven and unusually easy to measure, and it also makes it unforgiving. An enquiry that arrives four days before a start date and is answered a day later has effectively been thrown away.
The second defining feature is that almost every learner has a reason with a date attached. A visa interview, a university intake, a job offer conditional on a proficiency level, an overseas posting. The reason is not small talk, it is the qualification. Two learners asking about the same course, one with an interview in ten weeks and one who is curious, are completely different deals and should be worked in a completely different order.
Third, an institute usually runs two businesses at once. Individual admissions are fast, high volume and driven by batch dates. Corporate training is slow, larger, involves a proposal and a purchase order, and is won by a different kind of follow-up. Mixing them in one list makes the fast business look slow and the slow business look neglected.
