Pupils spend two years doing Nat 5s in our area, but the difference in when we start school here and the age cut off means your daughter will be a year behind.
for example I have a DC who has recently turned 16 and just completed Nat 5’s (our nearest equivalent to GCSE’s) and is now in S5 doing highers. I have a DN who turned 17 this week in England, just over a year older and did their GCSE’s before the summer (which would be the case for your daughter in 2026).
If your daughter had gone through the Scottish system, she would be in S4 now and sitting her Nat 5s in April/May 2025. She would then be going into S5 and starting her Highers in June 2025, before the summer holidays.
if you move her in spring 2025, she’s probably need to join the tail end of S3, go into S4 in June, then sit her Nat 5’s in April/May 2026, which is when she have been sitting her GCSE’s. So it would kind of work out, it’s just that she’ll be a year old than lots of her year group. She would have missed a year of the Nat 5 curriculum, but there will be crossover with the work she’ll be doing in her GCSE’s.
After Nat 5s, people do Highers in S5 (one year course) and then many stay on to do Advanced Highers.
it’s not a great time to move, but if it’s unavoidable, I’d be looking at study guides for the Nat5 courses and see how they compare to GCSE curriculum. Bear in mind also that schools here do 7 or 8 Nat 5s, which is fewer than the usual GCSEs.
Hope that helps!
