Agree on the two tiered WCAC...here here!
However, it is hard to blame the Archdiocese for a lack of support, when the only reason that ABC is still open is due to the ADW funding and DC School vouchers. It is very hard to run a Diocesan High school - especially when no one from the Diocese goes there. The four Arlington Diocesan Catholic schools are subsidized by the diocese, but all have decent to good enrollment numbers and decent alumni donations (no where near as good as the Gonzaga and STJ's, for a variety of reasons). When the Diocese opened SJPG in Dumphries, their calculation was that they needed 700-800 students for finacial solvency, and that is still with the diocese subsidzing them and donations. Carroll has what, 300-400 students? Numbers wise, that is a very hard number to sustain a school with at a Diocesan tuition level. The small private schools that are successful have tuitions in the 20k and higher range. Carroll raising its tuition that high is not going to achieve any results.
What most Catholic Dioceses around the country have realized is that with the skyrocketing cost of education, the lack of consecrated religious to teach, lower enrollments, and lower donations to the Church in general, is that they need to lean on the lay Church to help run the schools. Giving people buy in and ownership is crucial to keeping these organizations going.
That being said, Carroll needs a big push by its Alumni and community, with some more support from the Diocese. Also, CUA is right around the block - there should be a deep partnership with CUA. CUA students and grad students could help teach, CUA athletes and coaches could sponsor and develop corressponding sports, ABC students should be able to take college courses at CUA.....you get the picture. This would make ABC a unique offering and I cannot fathom why there is not a robust partnership.
