It is commonplace for parents to send their more academic offspring to the local secondary school and the less academic child to the local Tech.
We’ll send little Johnny to the Tech - they have a marvellous programme there for students with dyslexia!/ They’re very good at dealing with students who hated primary school/They’ve a lovely atmosphere there and little Johnny would thrive better there than in the local secondary where the atmosphere isn’t as “nice”.
Meanwhile, Patrick is sent to the local secondary school where he wastes too much time on religious indoctrination.
If the local secondary school dispensed with the religious indoctrination, they might do a lot better than they actually do. The Techs do very well indeed considering the cohort they generally get. In fact, if Mummy and Daddy sent their academic kids to the Tech, they’d probably do better there than in the local secondary, as less time would be wasted there in religious indoctrination.
