Junior Mathematical Challenge, UK Maths Trust

[Polyethyl]

Please can someone explain the standards needed for Junior Mathematical Challenge, UK Maths Trust?
My year 8 daughter got 46% in her end of year maths exam, which had us discussing summer holiday maths tutoring or a summer maths camp.
But she's come home from school this week with a Gold certificate from the UK Maths Trust.
So, do the Maths trust have very easy standards?
Or did she just have a bad day on exam day?

How can you get a gold in one test and a 46% in another test?

Grade boundaries vary year on year depending on the cohort performance. JMC paper was arguably harder this year so the thresholds were slightly lower - I tend to believe that as my DD who is not good at maths, not interested in it and did no prep still got a bronze.

Curriculum maths is different, JMC/JMO is more lateral thinking and creative maths so to speak. If your DD got 46% in her school exam, I would think it tells more about quality of teaching than JMC standards. School maths is pretty easy and straightforward if taught well.

On the 46%, find out what the other kids got. Sometimes they give a really hard test, a gcse past paper or something and don’t expect a high percentage correct.
My secondary kids always seem to know approx where in the class they came, what marks everyone else got. Don’t panic about one seemingly low mark.
As she got gold at JMC she is obviously very capable. At our school only top set even get to sit it and iirc gold is top 10%, so that’s top 10% of the top set kids…

Her best friend got 80% in the end of year maths exam, but she's a STEM enthusiast student, whereas my daughter is a linguist, so we don't expect her to match up to her mate. She doesn't know how the rest of the class did.

If a gold at Junior Mathematical Challenge is good, then I won't inflict holiday maths on her.
