We came here to live when the girls were 12 and 14.
These were what they found to be different in the negative:
Back home youngest DD was still in intermediate, so middle school. It was one hell of a shock to be tipped into a school with kids up to 17 years old! The very youngest at the school are so, so tiny next to the oldest.
The size of the school, and the noise level of the classes.
The lack of resources. The school's library was abysmal, and then closed. The laptops were out of the ark.
How other kids already felt funneled out of hope and progress by the education system. Having a select grammar nearby, and being a comprehensive academy, a lot of the kids seemed to feel that they were already failures, not having got into the grammar, and there was no point in pushing themselves academically.
The curriculum was so crowded with so many subjects, and so much pressure exams wise, particularly in GCSE years.
Most probably at least partially as a result of this, there was no room for 'whimsy', for experiences that encourage enjoyment of learning.
An absolutely bloody ridiculous focus on attendance as a metric, whereby if kids were sick as hell, they were still expected to attend school.
Ditto, this moronic authoritarianism about uniforms - if you're hot, you can't take off your blazer without permission.. REALLY?!
The loss of good, qualified teachers, trained in their subjects, passionate about teaching - not blaming the teachers, could totally see why they were going!
The casual misogyny in schools.
