Maybe 500 points higher than the student would be a good general rule. Although I have a student who is only 300 points weaker than I am
Also not true. On higher levels higher rated player can even learn from lower rated player. For example, 2400 can learn from 2300.
It's quite possible that lower rated player is very strong in one particular area(opening prep, planning skills, etc) where higher rated player is weaker.
A begginer can learn alot from a 500 player, and a 500 player can learn alot from a 1000 player. Jeremy Silman once said that some of the greatest chess teachers in the world are between 1400 and 1500 elo. Also, I struggle to belive a 2400 would hire a 2300 as their tutor. Most of the cases of a lower rated player working with a higher rated one are only at the very top level, and even then the lower rated player usually takes the roll of a trainer or second, rather than a "tutor" which is what the topic asked.
1) I donno, may be it's personal. But for me ... it's hard to imagine how 1000-rated player can tech ANYBODY! Also, hard to understand, how 1500 can teach 1000? I had an experience when players improved their rating from 1000 to 1300 in two months ... Then what? Change coach every two months ??? Sounds ridiculous! And, as I mentioned before, and B1ZMARK as well, bottom line is around 1800. Below this level people simply had a lot of missunderstandings and bad habits.
2) Can you please explain difference between "tutor" and "second"? You meant "tutor" is the teacher for complete beginners and "second" is strong player which helping another strong player to be better?
Meanwhile, did you know that:
"Usually chess players have seconds who are grandmasters, or at least International Masters. However, Hikaru Nakamura has a second who is rated just 2156. His name is Kris Littlejohn and he is Nakamura's second at just about every major event. "
