I ditto the pp.. and what I will add is that strong community is not only the students and teachers but also the parents, families and greater community. My 2 oldest are in an ELOB school and we parents MUST donate so many hours per month in order to have our kids there. This work is flexible and can be anything like computer stuff at home, driving on a field trip, help with expeditions and open house nights, etc..
What I really like about this is the fact that the kids are allowed a great deal of freedom in how they will learn something- for examle my ds1- last year in 1st grade had an expedition on dinosaurs and would need to learn about one type of dino to present to the community on open house night. The kids could write a story, write a song, make up a skit, make a 3-d dino, make a display of the dino in its habitat, etc.. anything really provided they included info about the era, diet, size of the dino.
The students and teachers then keep a portfolio of work and present it to the parents 2x a year so we together track progress, 2 other times a year we get written assessment based on a rubic- E-exceeds expectations of grade level M-meets expectations or N-Needs improvement -- this is the only 'grading' at the school- every paper and project is talked about and discussed with the teacher- not merely given a grade and sent onward.
Finally- no it is absolutely not christian based- it is based on the principles of outward bound - there are many christian like qualities, I suppose- ie- kindness, cooperation, community service -all done to better the quality of life of all involved..
We love our school and as previous HSers, it has really worked for us!!!
