Activities within the groups like marching and drills taught discipline and obedience to them and this succeeded to get the majority of the youth "politically programmed." Another success was that they managed to get Children pressurising parents to become a good Nazi and it seemed like at that time parents had no control over there children instead the Nazis had control over their children.
The Nazis managed to at first make the youth policy fun and exciting for children. Activities like singing, camping and playing games helped teach comradeship whilst still being fun and exciting for the youngsters.
The emphasis on physical training was a success in numerous ways for the Nazis. Children especially boys enjoyed the emphasis on sport and this meant that they put a lot of effort into it. In the longer run it meant that they were at an advantage physically over the British and French troops.
Successes stretched over girls as well as boys, it was reported that even Jewish girls wanted to join the BDM because it had such and appeal. It also bought all the class groups together and there was a feeling of equality throughout the BDM and Hitler Youth camps, which made children feel wanted and "part of something special."
Another way that the Nazi Youth Policy succeeded was by making their youth more charged up for war than any other nation; on the battlefield their soldiers that had been through the German Youth system fought "more fanatically" then the older soldiers.
Those were the clear successes of the Nazi Youth Policy however there were some failures to address. The first one is that even though in 1939 membership was compulsory to the Hitler youth, there was still 16% of the population who were not part of it. This showed that it had lost its appeal to some and the appeal to rebel was greater. Alternative youth Groups like the Edelweiss Pirates who stood against Hitler were growing in numbers and became a threat to Hitler's Volksgemeinscaft.
Also a social democrat reported that because the Hitler Youth had lost its fun and when it became compulsory there were reports of Youth leaders getting beaten up by the youth themselves. Showing that the youth were rapidly becoming rebellious and going against the Nazis.
Another failure was that many girls could not understand the racial science theory very few boys read "Mien Kampf" and were not impressed by the crude "Der Sturmer" both of which were supposed to implant the Nazi Ideology into the minds of the youth.
Another very significant failure was the education of the youth. Because of the Nazis intense focus on physical strength the new generation were become stupid and incapable of becoming a political leader or making any valid contributions scientifically or technically.
In conclusion it is clear that at first the Nazi youth policy was very successful and drew in a huge percentage of the German youth. However it is clear that like anything new and exciting, the novelty soon wares off. Rebelling against the Nazis was becoming more exciting than being part of them and the new alternate groups were growing in numbers as well. Also the Nazis clearly concentrated too much on the Physical state of the Nation rather than the mental state and it was clear that the new generation during Hitler's rein were way behind other counties in intelligence and this was a clear failure of the Nazis. One final point is that 12 years in power is not enough to indoctrinate the whole of the German youth and make them all give in to Nazi ideology.
