No, creative is not the way to go.
Imagine a DLA assessor. They get hundreds of forms, varying from just the claim form with no additional evidence (probably fine if a child is so clearly affected that they couldn't possibly get it wrong) to 2-inch thick bundles with every report going.
Their time is very pressurised. They have to get through the cases because they are being monitored.
They have very strict criteria, legally, that they assess claims against. Rough rule of thumb:
-Care needs of an hour per day (in excess of what would be reasonable for a typical child their age). Low Rate Care.
-Care needs frequently throughout the day (in excess), OR care needs only at night. Mid rate care.
-Care needs frequently throughout the day and at night, once for over 20 minutes or several shorter episodes. High rate care.
Now, detail is GOOD.
A 'story' with lots of unnecessary detail - NOT GOOD.
-You need clear, concise statements that show the level of care needed.
-You need to use appropriate words, preferably ones that are used in the Decision Makers' guide. Words such as 'guidance' 'supervision' 'requires' 'support' 'assistance', that the DM can mentally 'tick a box' against.
-You need to be explicit and unequivocal. Don't say 'tommy sometimes finds x difficult and wants me to help him'. Say 'tommy has difficulty doing x and cannot do it independently. He requires encouragement to do x, several explanations of the steps involved and support throughout the activity. If he doesn't get that support he will simply not do it. If he doesn't do it he will get sore skin....A typical child of Tommy's age would do x independently. They would not need supervision, support or assistance.'
It really isn't a 'game' of wits. It is just being able to write the truth, but write it so that it is crystal clear and cannot leave the DM confused.
