Any transfer brings changes.
Hand carry your most current IEP and evaluations with you to your new duty station. We would also suggest that you set up an appointment to talk with your child's current teachers. Ask them if there are any strategies or teaching techniques that have been of particcular success that they think should be continued. Many times it isn't only what information is provided but how it is taught that makes a difference to the student. Also some children need to use assistive devicies or supports, colored paper, tracking devices, etc.
