It's funny. You have created yourself a paradox. Replace comp sci with being a teacher. You have made the claim now that teachers can be incompetent but Johnny cannot be. Let's say Johnny wants to become a teacher and puts in lots of effort but just cannot teach. Now he is an incompetent teacher but at what point did he go from being judged on effort to being judged on ability? When he wanted to be a teacher and got a free pass for being a bad teacher? When he went for his first job and got a free pass for failing his exams? When his entire class learned nothing because he was unable to teach even though he put in lots of effort?
Where is the transition? At some point ability is more important than effort.
The paradox is only in your head. Do not confuse the process of learning a skill and practicing it professionally. The line between the two is beyond clear.
The question you refuse to answer is at what point should incompetencey be judged over effort. Little timmy who was always going to be a good teacher has now lost out because you the gave the position for the university place to little Johhny who everyone, despite all his everyone knew he was going to be a terrible teacher.
There is no benefit in always being praised for your efforts if you cannot deliver the goods.
I answered that and reiterated it. The outcome can be judged (and it is) when you do it professionally. Everything I said about evaluation on the effort was from the start about the learning process (the topic of this thread) and psychology in the critical formative period of young human’s upbringing.
