I don't have first-hand experience with this school district, but my advice would be to contact the Pleasanton ISD Special Education Co-op at (830) 569-1355. An administrator there will likely be able to provide more detailed information about what services are offered by the district and which school might be best fit for your child. Their website is also a useful resource. You might also be interested in taking a look at some of Noodle's articles and advice about special education and learning differences.
Hope this helps, and best of luck with your school search!
