The schools in the Harrogate area generally work to a catchment area. If you contact your local school directly they will be able to tell you if you are within their catchment area, they will also be able to give you details of any open days or their policy for visiting the school.
You may also want to read the school’s most recent OFSTED report to help you make your decision. Here
You may visit and or apply for a place at any school, however the admissions policy will outline who has priority (children with a statement of educational special needs, those with siblings in the school and those within the catchment etc) See your chosen schools website for full details.
