While there is a lot to say about the JW 'catechetical' program, I think it is a bit unfair to compare it to the apparent "instant baptism" pattern which might be gather from the book of Acts, which may cover a much more sophisticated (and certainly diverse) practice in the early church. Baptism was hardly ever the very first step of Christian initiation.
I get your point, but what I'm putting across is that the JWs, when contrasted with the early church, it's plain to see that believers didn't have to go through 'book studies' and undergo a series of questions before elders, but they were often baptized at the very instance they believed in Jesus. Within the JWs, baptism is certainly never rrushed into. Time passes where the 'candidate' will get through a fair amount of JW literature.
If a Christian wants to be baptised straight away, he or she can do so - - - JWs are not given that option! Examples of 'instant' baptisms in the NT are numerous and were usually a first evidence of their faith in Jesus. (Acts 2:41, 8:12, 8:36-38, 9:18, 10:47, 16:14,15,33)
Caliber -- lol
