TwoOddSocks,
IME, no.
If we just think about this practically - a non-NQT teaches their class 4.5 days a week, usually 5 mornings and 4 afternoons. They have 1 session of PPA - non contact time.
Unless BOTH of the mandatory 2 hours of PE are taught in that non-contact time, then the teacher has to teach the other at some point in their 4.5 days.
Equally, in multi-form entry schools, teachers in a single year group may have PPA together so they can work as a team (primary teachin can be an isolating business). It isn't efficient to have 2,3,4 sports coaches all working at once during the same non contact time.
Art the other end of the spectrum, some schools have only a couple of classes - would it be efficient to have 2 teachers + a sports coach in such a school? Money is short enough as it is in such schools.
My experience is that most schools use some external expertise for PE, some of the time - a sports coach working alongside class teachers while 1 of them has PPA, an gym coach coming in for a few weeks to offer CPD to a class teacher, a local sports club offering a few weeks of coaching a class at a time - but not for both hours of PE every week for every class on a permanent basis.
