I am familiar with the Briarwood Christian school (my nephews attend there) and investigated BTS a little bit, but it didn't fit my needs. I'm not sure that everyone here appreciates the need for non-traditional forms of education, especially for rural or small town churches. Let me explain why I perceive a need for schools such as BTS:
1. There is a huge segment of the country where bi-vocational pastors are the norm. These are usually gifted and willing men who have a "day job" but serve small and/or poor congregations. They need opportunities for training and education that allows them to continue in their employment.
2. There are some pastors/elders who have received their education earlier in life and have more recently been brought over to Reformed theology. I am in this number. The need is for them to receive organized training and instruction in a way that permits them to continue to serve their congregations.
3. Church people who are members at churches who are "reforming" need adaptable programs that enable them to be trained without uprooting their lives.
If I were thirty years younger, I would seek to attend the finest seminary I could afford. However, life circumstances as they are, I am unable to do so now. Instead, these non-traditional type of seminaries fit the bill and I am glad to have them. For me, it isn't about status, it's about availability/practicality.
To summarize: if at all possible, go to the best seminary you can afford. For the rest of us, take advantage of whatever sound, robust Reformed education you can get.
