School pages into the search engines - ?

According to webmaster tools, the SpellingCity page on First Presbyterian Church School is not listed. I'll do a google search to see whether this school can be found on SpellingCity.com: First Presbyterian Church School site:SpellingCity.com. The answer is that while some other school pages are found which have links to that page, First P's home page is not yet in the Google index.

Why isn't First Presbyterian Church School's home page on SpellingCity.com in the index?

This is weird in that:

1. There are at least two schools that I found that link to this home page which have links to them from their schools (Tinsley Elementary School & Greenville Elementary School). Of course, the links at the bottom of these pages in which the local schools link to each other should ideally have well-less than 100 links on the page. Unfortunately, these pages seem to have about 260 other schools listed which could account for the links not being counted.
2. There are two blog posts from twenty days ago which have direct links to this First Presbyterian Church School. School pages not appearing and School home pages.
3. I have been hoping that this page would appear in the index and mostly, my dreams do come true.

Any ideas? Since we have 125K school homepages that we're hoping will begin to get listed, this is a question of some importance. I could imagine that Google is reluctant to include these pages since they are short on content and links. Still, over 5K of these schools have links directly from the schools to them so it's hard to imagine why they don't get listed. Maybe, too many of these links are images?
