The number of special education students moving into Keller schools is growing rapidly while resources are on the decline, according to district officials.“We have 400 new students in the district this year and 200 of them are special education students,” said Janette Hahn, director of special education.In spite of the additional students, the amount of federal funding Keller receives for special education is dropping, from more than $7 million in 2009-10 to $3 million this year.At the Oct. 17 board meeting, Hahn told trustees that the district had nine special education classrooms with urgent needs for an additional aide because of the increase in enrollment. Those positions have been posted. Another 13 classrooms will need another assistant if one more student is placed.Hahn said that the 200 students was only those moving into Keller from other districts. Since the beginning of the year, KISD educators have been identifying students who may need special services. Every month, the Keller Early Learning Center holds screenings for preschool children who may need services. Hahn said that of 30 preschoolers screened in October, 27 of them likely qualify for assistance.Students receiving special education services range from severely disabled, medically fragile children to preschoolers taking speech therapy classes. More than 3,000 students in Keller schools receive services compared to about 2,600 in 2011-12.Superintendent Randy Reid said the increase is not coming in students with learning disabilities but in the higher needs categories requiring special classrooms and resources. Students who are struggling in academics typically are served through pull-out programs while in regular education classes for most of the school day.Hahn said that the area growing fastest is in services for students with autism.The more severe the disability, the smaller number of students can be served in the classroom. Hahn said that medically fragile students typically need more equipment and more personnel.KISD administrators are looking to establish a pool of aides who would be available if more high needs students move into the district. Hahn said her department also would like to add a clerical worker due to the large paperwork demands that come with the growth.
