A Good School Mean Kyokushin Karate Dojo and as you know kyokushin is the most Disciplinary karate in the world.
You must look for a kyokushin School and a good kyokushin school means that you should have a experienced kyokushin teacher with Original Certificates from Japan and years of Experience.
School Shouldnt have many Students but a limited students so that the Instructor pays more attention to every Individual student.
School Must have a proper attendance system and should get the proper class as scheduled.

I have had many years experience in training in a number of martial arts styles. My advise to you would be to seek out a style that suits
(a) your body type
(B) the level of contact training you are comfortable with
(C) the instructor demonstrates a high level of committment to his/her students.

Not all martial artists are looking for the same thing from their training, some want fittness others fighting skills and others flexability. You need to assess what it is you want from training and then decide which style is best suited to your particular needs.
Hope you find a good one

Nice Suggestion you are doing a fine job you are welcome on forum

Well, I would have to say. Look for a teacher who actually participates in the class. Not a teacher who just sits there and watches you do the exercise. Look for authentic certificates from Japan, and ask him questions on the history of his art. Look for a Dojo that is traditional and trains hard, not just a few exercises here and there. You want to sweat in class, train hard.
But as Tetsui said, look for a Dojo that best suits your needs and capabilities as well. And whatever Dojo you choose, make sure you train to the best of your abilities in it.

Osu!

Nice Suggestion Goju You are Earning Respect on the Forum and I totally Agree with you the Instructor who takes Class and have proper and authentic certificates from Japan the Dojo Must have Strict Discpline and the Junior must Respect the Senior and the Senior Must Also Give Respect to Junior It Shouldnt be one sided the both must respect eachother and help eachother while training and there must be no Gossip in dojo which I have seen in many dojos
thanks

I am very glad to be of service to fellow Karate-ka. We should all help each other, we are a big family!

Osu!
