As of my last knowledge update in January 2022, I don't have specific information about a school called "GMIS" (Greater Manchester Independent School) in the United Kingdom. It's possible that the school you're inquiring about might have a different name, be a relatively new institution, or have limited publicly available information.

To obtain accurate and up-to-date information about GMIS or any other school, I recommend doing the following:

1. Visit the Official Website: Check the official website of GMIS if it exists. School websites typically provide comprehensive information about their programs, curriculum, admissions, staff, and contact details.

2. Contact Educational Authorities: Reach out to the educational authorities or local government departments responsible for school registration and oversight in the Greater Manchester area. They can provide information about accredited schools in the region.

3. Local Directories: You can also check local school directories, educational guides, or directories provided by educational associations or councils in the Greater Manchester area.

4. Contact the School: If you have specific questions about GMIS, you may try contacting the school directly via email or phone to inquire about their programs, admissions procedures, and any other information you need.

Since my information might be outdated, these steps should help you find the most accurate and current details about GMIS or any other school you are interested in.
