1. Beginner/Improver - never played or played a little. At best can rally a little in the service boxes, not full court. Serves most probably not working yet and no volley technique.
2. Intermediate - this player is ready to start playing singles. They have some consistency on groundstrokes as they are just about able to rally. They can also serve but most commonly do not have much ability to volley. LTA 10.2 & 10.1
3. Advanced Intermediate - like above can hit a reasonable volley and play some basic 1 up 1 back doubles. LTA 9.2 & 9.1
4. Advanced Recreational - as above, plus this player has fairly good groundstrokes and can use spins and some control over shots, can rally backhand to backhand with a player of similar level. Better doubles play, most probably still 1 up 1 back. LTA 8.1 & 8.2
5. Low Club Level - as above with more consistency and ability to play singles and doubles, with more shot development. LTA 7.1 & 7.2
6. Middle Club Level - as above, tactically better in both doubles and singles, with more depth on strokes. Club team player in 3rd/4th/5th team in larger club (depends on club size and player depth). LTA 6.2 & 6.1.
7. Good Club Level - improved player than above, more consistency and/or aggressive play that works. 2nd/1st team player depending on the club. LTA 5.2 & 5.1
8. Top Club Level - improved player due to more match-play experience and better strokes and tactic awareness across singles and doubles. 1st team player in most clubs. LTA 4.2 and up The old LTA scale I have included as many people are familiar with the old ratings, more so than the new ones.
There are many levels above this before you would get to a player who qualifies for futures tournaments, then world rankings come into affect.
