Those tables are pretty clear on what novice, intermediate, advanced, and elite mean, and pretty accurate for full lifts without gear. Between Pendlay, Rippetoe, and Kilgore, I would imagine they have a pretty decent handle on what constitutes what for the different categories.
Untrained
Expected level of strength in a healthy individual who has not trained on the exercise before but can perform it correctly. This represents the minimum level of strength required to maintain a reasonable quality of life in a sedentary individual.
Novice
A person training regularly for a period of 3-9 months. This strength level supports the demands of vigorous recreational activities.
Intermediate
A person who has engaged in regular training for up to two years. The intermediate level indicates some degree of specialization in the exercises and a high level of performance at the recreational level.
