The functional impact of how you are affected by ME/CFS is assessed via a set of impairment tables through which you score points according to your level of disability. Each symptom, or level of symptoms, need to be evidenced by a medical practitioner. 

Currently, you need to score at least 20 points to be eligible for the DSP. The impairment table ‘Functions requiring physical exertion and stamina’ is usually the most relevant for people with ME/CFS. 

If you score 20 points or more in a single table, you do not need to complete a Program of Support and you should be assessed as having a Continuing Inability to Work (CITW). 

If you score 20 points across more than one table (but do not score 20 points or more within a single table), you should be eligible for the DSP, but you will need to complete a Program of Support. You will also need to be assessed as having a Continuing Inability to Work (CITW). 

You may also need to attend a Job Capacity Assessment and a Disability Medical Assessment.
