Iac: you missed my point. Once you teach the trup why are you “teaching” and only 4 or 5 pesukim per week. I don’t pretend to be a teacher, it happens to be that I’ve taught a few kids full parshiyos with haftorah, but when I was taught the 1st week was dikduk the 2nd week was the trup until I actually understood that the symbols symbolize a time. And the 3rd week we put it all together and we learnt a full aliyah. My parsha is shoftim which is a small parsha and I knew the basics of leining before so I’m not expecting everyone to be this quick, but it took me 7 weeks for the parsha and my teacher told me to listen closely to the bal koreh in shul for the haftorah trup so it took me another 2 weeks to master. The whole thing was 3 months. If your “teaching 3 or 4 pesukim a week” it has to be that your not doing a good job teaching. The best way to learn is for the kid to figure out the leining on his own. I used to come to my lessons every sunday having mastered the next aliyah and my teacher used to go it over with me and point put little mistakes.
To sum up what I’m pointing out: if he is not preparing by himself he’s a parrot and if he ever wants to lein again he’s gonna have to do the work (which your being paid to teach) on his own. I’m also proud to say that the half dozen kids that I’ve taught have all leined again shortly after without my help learning a new parsha because they already new how to lein!
