ADP Descriptors Explained: How the Right One Is Chosen

When people talk about scoring points for Adult Disability Payment (ADP), what they really mean is descriptors. A descriptor is the building block of the whole system. Get to grips with how descriptors work and how the right one is chosen for you, and the rest of the ADP scoring falls into place. This guide explains what a descriptor is, the rule that decides which one applies on most days, why only one can score per activity, and how reliability quietly pushes you up the ladder. Two worked examples show the mechanics in action. For a condition-specific example, see ADP for hearing loss.

These descriptors are set out in law, in The Disability Assistance for Working Age People (Scotland) Regulations 2022, Schedule 1. Adult Disability Payment broadly aligns with the benefit it replaced across the rest of the UK, so the descriptors are worded the same. What is genuinely Scottish is how they are applied: your case is normally decided on the papers, so the descriptors are matched to what you write rather than to a face to face test.

What a descriptor actually is

Each of the 12 ADP activities has its own short list of statements, and each statement is a descriptor. A descriptor describes one level of difficulty and carries a fixed number of points. The lowest descriptor in every activity describes doing the task with no difficulty and scores 0. The points climb as the difficulty rises, up to 8 points in most daily living activities and up to 12 points in the mobility activities.

Your case manager at Social Security Scotland reads your Adult Disability Payment application Part 2, along with any supporting information, and selects the single descriptor in each activity that best fits how you cope. Nothing is ticked by you in advance. The descriptor is the conclusion the case manager reaches from your description, not a box you choose.

The rule that decides which descriptor applies: most days

Here is the part that trips people up. Within one activity, only one descriptor can score, even where several are true of you. If you can manage a task one way on Monday and a harder way on Wednesday, the case manager does not add both. They ask a single question: which descriptor applies to you on more than half of the days?

This is the most days rule, sometimes called the majority of days test. It is judged over a typical period, not a single week, so a condition that flares and settles is looked at across the whole pattern. If a higher scoring descriptor is true for you on the majority of days, that is the one that counts, even on the better days when you can do more. If no single higher descriptor reaches the majority on its own, the case manager works out which level of difficulty you are at on most days and applies that.

How reliability moves you up the ladder

Before a case manager can say you meet a lower descriptor, they have to check regulation 7. This says you can only be counted as able to do an activity if you can do it safely, to an acceptable standard, repeatedly and in a reasonable time period. Fail any one of those four tests on most days and you are treated as unable to do the task that way.

Reliability is often what separates one descriptor from the next. Two people might both physically get dressed, but if one of them can only do it by resting halfway, taking three times as long, or with a real risk of falling, they are not doing it reliably. That person moves up to a descriptor for needing an aid, prompting or assistance. Always describe not just whether you can do something, but at what cost, how long it takes, whether it is safe, and whether you could repeat it later the same day.

Worked example: preparing food

The preparing food activity is a clear ladder from no difficulty to no ability. The descriptors run like this.

Say your hands shake and your balance is poor, so you cannot safely stand at a hob and handle boiling pans, but you can heat ready meals in a microwave. On most days that matches the microwave descriptor, worth 2 points. Now suppose that on the majority of days your concentration is so poor that you leave the microwave running, wander off and forget the food entirely, so you are not safe without someone watching. That is supervision, and the higher descriptor at 4 points now applies instead. The case manager takes the higher one that is true on most days, not both.

The same reasoning applies to aids that only work for part of the day. A scleral lens can make reading possible for a few hours and impossible after that, which is a "repeatedly" failure rather than an outright inability. Our guide to ADP for keratoconus works that example through.

Worked example: moving around

The mobility activity of moving around is scored on distance, and it shows how a single descriptor is picked from a graded ladder.

The distance that counts is the one you can manage reliably, so safely, to an acceptable standard, repeatedly and in a reasonable time. If you can force yourself to 60 metres once in the morning but are then in too much pain to repeat it and cannot do it at all by the afternoon, you are not covering that distance reliably. The honest descriptor may be the 20 to 50 metre band rather than the 50 to 200 metre band. On most days, the shorter reliable distance is the true one, and it carries more points.

Why the Scottish process makes descriptors matter more

In Scotland most determinations are made on the papers, without a consultation. That makes your written description the main thing the case manager has when choosing your descriptors. Social Security Scotland has a duty to help gather supporting information, and a case manager can request it directly from the people you name, so a letter from your GP or consultant that confirms a condition responsible for more than a minor part of your needs can anchor the descriptor you meet. One reliable piece of formal information can be enough. You do not need to argue the law. You need to describe your life clearly enough that the right descriptor is obvious.

Frequently Asked Questions

What is an ADP descriptor?

A descriptor is one of the numbered statements under each of the 12 activities. Each describes a level of difficulty and carries fixed points, from 0 up to 8, 10 or 12. Your case manager matches what you write to the one descriptor that fits how you cope on most days. They are set out in The Disability Assistance for Working Age People (Scotland) Regulations 2022.

How is the right descriptor chosen for me?

Only one descriptor scores in each activity, and it is the highest scoring one that applies to you on more than half of the days over a typical year. Where different levels of difficulty apply on different days, the case manager looks at which is true on most days.

Can I score points from more than one descriptor in the same activity?

No. Within a single activity only one descriptor scores, even if lower ones are also true. You do add points across different activities to reach the 8 to 11 standard or 12 or more enhanced thresholds. See the points system guide for the full sum.

What does most days actually mean?

It means true for you on more than 50 per cent of days, judged over a typical period rather than one week. A condition that flares and settles is looked at across the whole pattern, so if you cannot do something reliably on most days you meet that descriptor even on the days you manage.

How does reliability affect which descriptor applies?

Regulation 7 says you count as able only if you can do the task safely, to an acceptable standard, repeatedly and in a reasonable time. If you can only manage by taking far too long, at risk of harm or not properly, you are treated as unable that way, which usually lifts you to a higher descriptor.

Should I pick my own descriptors on the form?

No. Part 2 does not ask you to tick descriptors. You describe in your own words how each activity affects you on good and bad days, and the case manager matches that to the descriptors. The fuller your description, the more accurately the right one is chosen.
