With my DS's EHCP's we've always set 1 year measurable objectives.
So at 4 his objectives might have been to enter school in an appropriate manner, eat his lunch at a table of his peers, mark make/ write and identify his name, use appropriate adaptations to assist him with the school environment.
Then there would be a resource and plan of action sentences for each of these.
Initial handover to TA who will supervise coat on peg, sitting at desk. Use of storyboarding by TA to help the learning curve and understanding of behaviours.
Mark making might have daily activities for 20 min supervised muscle strength building by TA action plan and training by OT
Sometimes tasks are longer term and on going but its kind of your what you/ school think are priorities to work on. By using measurable when you have your annual review you can request further funding if these aren't being adequately met.
Regarding funding in my area we use task based information in EHCP's but I was chatting to a very interesting lady from out of area at a NAS session and she told me that in her area you could apply to get the money allocated direct and manage the fund yourself paying for the OT and other therapists etc rather than school dictating. Sounded very progressive but I have had a great relationship with DS's last 2 schools so it's not been necessary. There were three schools before that, it's taken time to learn the system and get things right.
