Preparing for a formal cognitive assessment
A formal assessment isn't an exam you can revise for, and trying to would undermine it. Preparing well means arriving rested, informed and ready to describe your situation accurately.
What preparation actually means here
Prepare by sleeping normally, eating beforehand, bringing glasses, hearing aids and any relevant reports, listing your concerns with examples, and clarifying the purpose of the assessment. Don't practice test items: standardized results assume unfamiliarity, and practice distorts them. Tell the assessor about anything affecting you on the day, such as illness, medication changes or poor sleep.
Before the appointment
| Task | Why it matters |
|---|---|
| Confirm what the assessment is for | Shapes which tests are used |
| Ask how long it will take | Often several hours, sometimes split |
| Sleep normally the night before | Fatigue affects attention and speed |
| Bring glasses and hearing aids | Sensory issues can distort results |
| Gather previous reports | School records, medical letters |
| Write examples of difficulties | Concrete instances help more than general statements |
What typically happens
| Stage | What it involves |
|---|---|
| Interview | Background, history, current difficulties |
| Testing | Subtests covering verbal, reasoning, memory, speed |
| Breaks | Standard in longer sessions |
| Feedback session | Discussion of results and recommendations |
| Written report | Scores with confidence intervals, profile, recommendations |
Why practicing items is a problem
Standardized scores are interpreted against norms built from people who hadn't seen the items. Practice inflates performance on those specific tasks, which can distort the profile and, in some cases, mask the very difficulties the assessment is meant to identify. If you've taken the same test recently, tell the assessor: intervals between administrations exist for this reason.
Questions worth asking
| Timing | Question |
|---|---|
| Before | Which tests will you use, and what will the report cover? |
| Before | How should I prepare, and is there anything I shouldn't do? |
| On the day | Can I mention anything affecting me today? |
| After | What do the confidence intervals mean for my scores? |
| After | What are the practical recommendations? |
On the day
Arrive with time to settle. Tell the assessor about any sleep problems, pain, medication changes or anxiety. Ask for a break if you need one. Effort matters: standardized tests assume you're trying, and assessors often include measures of engagement.
