In 2013-2014 school year, 6.5 million children ages 3-21 received special education services which constitute almost 13% of total public school enrollment. Throughout the last two decades, particularly from 1990 through 2004, the number of students ages 3-21 who received special education services, increased from 11% to 14% of total public school enrollment. Educators during this period have tried to include students with disabilities into more inclusive settings as a response to the No Child Left behind Act (NCLB, 2001) and the Individuals with Disabilities Education Act (IDEA, 2004). This movement has increased the number of diverse students in inclusive settings.
