There are several concurrent threads about these severity levels. This is how the DSM manual looks at it. I assume level 1 is equivalent to "mild", level 2 is equivalent to "moderate" and level 3 is equivalent to "severe". Individual clinicians interpret this manual as they please or use the ICD manual. They at times give out the diagnosis not listed in the manuals such a "high functioning autism". Despite all the confusion and problems, this is a rough guide as to what is meant by "mild", "moderate", and "severe" autism

Severity levels
Level 3
"Requiring very substantial support”
Severe deficits in verbal and nonverbal social communication skills cause severe impairments in functioning, very limited initiation of social interactions, and minimal response to social overtures from others. For example, a person with few words of intelligible speech who rarely initiates interaction and, when he or she does, makes unusual approaches to meet needs only and responds to only very direct social approaches
Inflexibility of behavior, extreme difficulty coping with change, or other restricted/repetitive behaviors markedly interfere with functioning in all spheres. Great distress/difficulty changing focus or action.
Level 2
"Requiring substantial support”
Marked deficits in verbal and nonverbal social communication skills; social impairments apparent even with supports in place; limited initiation of social interactions; and reduced or abnormal responses to social overtures from others. For example, a person who speaks simple sentences, whose interaction is limited to narrow special interests, and how has markedly odd nonverbal communication.
Inflexibility of behavior, difficulty coping with change, or other restricted/repetitive behaviors appear frequently enough to be obvious to the casual observer and interfere with functioning in a variety of contexts. Distress and/or difficulty changing focus or action.
Level 1
"Requiring support”
Without supports in place, deficits in social communication cause noticeable impairments. Difficulty initiating social interactions, and clear examples of atypical or unsuccessful response to social overtures of others. May appear to have decreased interest in social interactions. For example, a person who is able to speak in full sentences and engages in communication but whose to- and-fro conversation with others fails, and whose attempts to make friends are odd and typically unsuccessful.
Inflexibility of behavior causes significant interference with functioning in one or more contexts. Difficulty switching between activities. Problems of organization and planning hamper independence.
If clinicians followed the manual strictly a person with autistic traits who masks successfully SHOULD not be diagnosed and a person who is "severe" should not have the ability to post here.
IMHO among other problems, there is too much emphasis on physical presentation. What if a person cannot do "a few words of intelligible speech" but can text ok?
