You should contact school district office in your community and request information about an intradistrict (within the same district as your "home" school) or an interdistrict (outside of your "home" school district). The paperwork varies between each district office with different forms and processes.
There is also a great degree of variability as to whether your transfer application will be approved. For instance, if you are applying to transfer to a school that is already highly impacted, your application may be declined because there is no room for your child. However, if the school that you want to transfer to has special services that your "home" school does not provide (e.g., special education services), your application has a better chance of being approved.
