My ds is also 7, in Y3 and HFA. His statement is slightly different from the norm as we fought to get ABA in at the start, just when he started school, and he still has 25 hours support written in though he really doesn't need it, nor gets it exclusively (which is fine by me). It now has a management plan built in which should be followed by any TA, covering every aspect of his life at school.
The crucial things for me are all about the social interaction side. A statement doesn't just hae to cover any academic support, or just support the classroom, but also playground time. My ds is very sociable and has friends, but finds it hard (obv!) to interact normally, can overreact, misunderstand rules of games, etc. Our plan covers support for all of this, and not just someone following him around babysitting for signs of trouble, but proactive sessions during break times, with peers, working on key social targets. Almost like informal drama sessions actually.
He also does (or should have if school get their act together) have SLT to work on social skills too.
But presumably you've had EP and SLT reports? All their recommendations of course must go into part 3 too.
Our main Learning Objectives are roughly:
To develop effective communication system
Develop social skills including accessing greater range of social contexts, develop meaningful friendships, and appropriate social interaction with peers
Develop play skills, both symbolic and social
Self -help skills
Develop capacity to manage change and transition
Develop awareness of safety and environmental risks
So with ours, all of these objectives are broken down into detail, and everything is done according to a based behavioural management plan, based on positive-reinforcement (ABA) approach.
