An FCA appointment takes place at one point in time. When your condition varies, the assessor needs information about the pattern beyond that appointment.
That may mean comparing days, episodes or a longer period. The useful timeframe depends on the condition and the decision the assessment needs to inform.
Describe the variation
Explain which activities change and how. You might manage a task on some days, need help on others, or complete it but be unable to do another activity afterwards.
Frequency and duration matter. A difficulty that occurs every morning needs a different explanation from an episode that happens several times a year. Give estimates where that is all you have, and make clear that they are estimates.
The report should include more manageable periods as well as difficult ones. It needs to explain the range, not select whichever day appears to make the strongest case.
Include assistance and recovery
Support may partly explain why an activity appears consistent. Someone may organise the task, take over part of it or help you recover afterwards. Equipment and a familiar environment may also affect what you can do.
Where relevant, describe the time or consequences after an activity. For example, attending an appointment might be possible but affect meal preparation later that day. This is an illustration of the kind of connection an assessor may explore, not an assumption that every person experiences it.
Being able to take part in the interview does not establish what you can do across the rest of the day.
Use records that are already available
A brief note of recent examples can help you remember the pattern. Existing appointment records, support notes or treating reports may also be useful when they address the question being assessed.
If a particular assessment requires monitoring over time, the assessor should explain what is needed and why.
When completing a questionnaire, follow its stated timeframe and instructions. Do not replace an average-period answer with your worst-ever episode. Describe a longer or unusual pattern separately so it can be interpreted appropriately.
What the report should explain
The report should identify the period considered, the sources of information and any uncertainty about the pattern. It should explain how variation affects activities and what support is required in different circumstances.
A fluctuating condition may involve an enduring impairment, but that conclusion needs appropriate evidence. An FCA's account of activities does not replace evidence about treatment or permanence where those matters are required.
The aim is an account that remains useful when the day of the interview is no longer representative.
