Low expectations are nothing to do with their career choices - our son chose to not go directly to university and we fully supported that. He did, however have the academic qualifications to do so - we knew it was actually an informed choice rather than ‘dunno, what can I do with a D and an E’?
It’s about ensuring what they do is actually a choice rather than a fall-back because the parents were too indulgent to support maximum achievement. A happy fifteen year old, who is cool, who chills with their friends may find they aren’t the happy, well adjusted, thriving and economically stable thirty year old. Clearly not all children can get exceptionally high A level or IB grades, but they absolutely can be supported to get their best grades.
One of our foster sons couldn’t read when he arrived and went to a special school. He’d been damned by parents who let him do his own thing - that thing involved hanging around, messing with a group in low level criminal activities, smoking and damaging the environment. His achievement wasn’t A levels but it was literacy, numeracy and onto City and Guilds qualifications that has allowed him to set up his own vintage vehicle renovating business. We are as proud of him as our other children.
Nothing to do with being a barrister or doctor - all about what choice actually means for an eighteen year old. Interestingly, few with high grades choose to go into bin collection or become shop assistants long term. I’m sure a few do, but most want the nice things in life and to be comfortable. That requires effort unless you’re born with a silver spoon.
