Thank you Rabbi Grumet for your important survey. There are 2 issues where I think we need to be cautious in terms of what conclusions to draw from the data.
1] While the survey did compare the participants' current observance levels to what they perceived as their parents' in terms of shabbat and kashrut, it did not do so for issues of intimacy and dogma. The role of the home is critical to any discussion of how the educational system is doing. If someone comes from a home where the parents do not think that being shomer negiah is a value, I think it's unrealistic to think that the school will convince them otherwise. The same holds true for issues of dogma. Before concluding that schools need to put effort into teaching dogma, I think a study need to be done to see if what they are teaching is in sync with the message from home.
2] Rabbi Grumet concludes that most of the survey's participants are Orthoprax. I believe that is an unwarranted conclusion. He didn't ask them more general questions, like do they believe in Torah MiSinai, is the Torah divine, he asked them more nuanced ones which, while important, are a far cry from what Orthoprax stands for.
