The best known resource, although not a blawg is Wrightslaw.com. The amount of energy and time that Pete and Pam Wright and their staff put into this massive site is incredible. Despite the fact this site has been around for many years, some parents are not familiar with this site which should be the starting point for any parental research project in the area of special education advocacy; this site will provide access to case law, understanding educational methodologies and evaluations, just to name a few.
One of my personal favorites in the strictly blawg category is the Disability Law Blog. This site is hosted by a law professor from Washington University (my undergraduate alma mater) Law School, and it shows. The articles are thoughtful, useful and not just designed for attorneys. The postings are incredibly timely and have commentary that help put the topic into perspective and context.
The blawg that inspired me to start my own blawg is Fapepage. Although the postings are not daily (as has been my bane recently as well), the author comes up with some gems of case law and is always a worthwhile read for topical information that sometimes gets overlooked else where. Sandy Hausler is also a very nice person and has generously shared much information with me.
Dorene Philpot, who recently moved from Indiana to Texas, which is a loss for families in Indiana, has a wonderful website that is chock full of resources and some selected humor as well. It is a good site to check out especially for guidance and case law in the 7th Circuit.
Another site to look to for statutory and regulatory references and many special education resources, especially for those in New Jersey is from Sussan and Greenwald. This site is well organized and updated frequently with case law both state (N.J.) and Federal. I particularly like the autism study they have linked at their site. There is a solidness about this site that inspires confidence that the information is accurate and not over done.
Any parent or special education professional that consulted any or all of these sites in addition to this site would be well armed for advocacy on behalf of a child with special needs.
