LFA is can seen from an IQ-based perspective. For example, many psychs classify people with HFA as someone with an IQ greater or equal to 70. Someone with an IQ of 69 and below is often classified as LFA. IQ can be difficult to measure in people with autism, and probably shouldn't be the only consideration when classifying people. Carly Fleishmann from the previous post was, I believe, diagnosed with mental retardation as well. She is considered LFA, but now that she is able to communicate, I believe she could score higher on an IQ test. I might be wrong, but she really seems quite intelligent.
LFA and HFA are also distinguished by how much capacity you have for success and toward self-help skills. It is important to remember that HFA does not mean someone is mild. My psych classified me as two things: I am HFA because of my IQ and the fact that I can go to university. But really, I have moderate classic autism. I am far from mild and depend on other people a lot (I actually see myself as either moderate-functioning, or severe high-functioning). HFA might be mild--they might be married, have children, have friends, and be highly successful in their jobs. On the other hand, a HFA person might also live in a group home, need help with cooking, cannot drive, and have no friends (yet can still feed themselves, dress themselves, etc). LFA need help with many of these skills that HFA can usually do on their own.
Edit: I forgot to mention that one of the other classifiers is a person's ability to speak. Often non-verbal are lumped in with LFA and verbal with HFA. Keep in mind again though, that being verbal certainly doesn't mean mild.
