Shalom Nina! My understanding of what is leads to baptism is based on what I see in scripture: belief, repentance, desire.
I took had a church tell me I had to wait, had to prove I understood what it meant, had to write out a testimony and read before the people.

Here is what scripture shows is required:

He that believes and is baptized shall be saved; but he that believes not shall be damned. MARQUS (MARK) 16:16 את CEPHER

And as they went on their way, they came unto a certain water: and the eunuch said, See, here is water; what hinders me to be baptized? And Philip said, If you believe with all your heart, you may. And he answered and said, I believe that Yahusha Ha'Mashiach is the Son of Elohiym. And he commanded the chariot to stand still: and they went down both into the water, both Philip and the eunuch; and he baptized him. MA'ASIYM (ACTS) 8:36-38 את CEPHER

Then Shim`on himself believed also: and when he was baptized, he continued with Philip, and wondered, beholding the miracles and signs which were done. MA'ASIYM (ACTS) 8:13 את CEPHER

Then Kepha said unto them, Repent, and be baptized everyone of you in the name of Yahuah-Yahusha for the remission of sins, and ye shall receive the gift of the Ruach Ha'Qodesh. For the promise is unto you, and to your children, and to all that are afar off, even as many as Yahuah Elohaynu shall call. MA'ASIYM (ACTS) 2:38-39 את CEPHER
