Expert writing Tips
Best practice
Always use the possessive form "person's" or "individual's" instead of the plural "persons" when referring to a single person's level of functioning. This corrects a common grammatical error.
Common error
Avoid using "persons" when you mean "person's". "Persons" is the plural of person. Instead, use the possessive form to indicate that it is the level of functioning of a single individual. For example, say "the "person's level of functioning"" not "the persons level of functioning".
