What u Pay is WHAT U GET !
Not necessarily.
Unfortunately there are many out there that charge a fortune and give you nothing.
Then there legitimate teachers.
1. Ask the owner of your studio what the training background is of your personal teacher. Are you being taught by a trained and certified teacher or are you being taught by a relatively new teacher the owner trained themselves.
2. You might also look into private teachers. Again, ask about there certification. I don't know where you live but trained teachers here have either ISTD or CDTA certification. Other certifications should closely match ISTD (for International) criteria.
Hint: ISTD certification requires years of study. You can't whip it off overnight.
Note: Just because a person doesn't have certification doesn't mean they are not a good teacher but it is a sign they have met a minimum standard.
