Somebody enrols in a weekly evening class hoping to hold conversations on holiday in eight months. It seems reasonable and nobody corrects it.
A weekly ninety minute class over three terms is a modest number of guided hours, during which she speaks for a fraction of the time, with no practice between lessons.
Eight months later she can order food and cannot converse. The class was good, the expectation was never achievable, and nobody did the arithmetic with her at the start.
What determines how long it takes
Four things. Guided hours, speaking time within them, independent practice between lessons, and the distance between the learner's own language and the target.
Component 1: guided hours
Total class time. This is the number schools quote and it is the smallest part of what actually produces progress.
Component 2: speaking time within those hours
Total class time divided by class size, roughly. In a large class this is a small fraction of the total, and it is the number that actually drives spoken fluency.
Component 3: independent practice
What happens between lessons. This is where most progress actually occurs and it is entirely within the learner's control.
Component 4: the language distance
Some languages take considerably longer from a given starting point than others, which is a real factor and rarely mentioned.
A worked example
A ninety minute weekly class over thirty six weeks is fifty four guided hours. In a class of twelve, individual speaking time might be four or five hours across the whole year.
The same year with practice
Twenty minutes of practice five days a week adds around sixty hours over the same period, more than doubling the total and shifting the speaking time enormously.
What the arithmetic shows the learner
That the class is a framework and the practice is the engine. A learner who understands this progresses, and one who expects the class to do it does not.
State an honest expectation at enrolment
What somebody can realistically do after a term, a year and two years at a given commitment. This prevents the disappointment that ends most language learning.
Explain the intensity option
An intensive course achieves in weeks what a weekly class achieves in a year, which suits some people and some deadlines, and it is rarely presented as a choice.
Explain what plateaus look like
Progress is fast at the beginning and slows at intermediate level. Learners who are warned about this continue and learners who are not conclude they have stopped improving.
Show the cost per hour honestly
Total course cost against guided hours, and against realistic speaking time. This lets somebody compare properly rather than on a term price.
Explain what a level actually means
In terms of what somebody can do rather than a framework label, because that is what a learner is actually trying to buy.
Do the arithmetic with the learner at the enquiry
An assistant that asks what somebody wants to be able to do, by when, and how much time they can give between lessons can state an honest expectation and recommend the right intensity rather than the default weekly class. The level questions sit in level test and course questions from language learners, the parent version in junior summer courses and parent questions, the same honest duration setting in session count and course questions, and the time arithmetic in the hidden hours you lose to repetitive questions.
