From Texas Standard:
Since the 1970s, federal law has stated that all children with disabilities are entitled to a free public education appropriate to their needs. Nationwide, the percentage of kids who receive special ed services is around 13 percent.
But in Texas, that number is substantially lower. Just 8.5 percent of all public school kids in Texas are enrolled in special ed programs – the lowest percentage in the country. That number appears to be no mere accident – instead, it’s a rather specific objective.
