Supplementary forms are common in faith and selective admissions. This guide explains how to approach them without missing the main application.
Understand what the extra form does
A supplementary information form, often called a SIF, gives a school the extra information it needs to apply particular parts of its admissions policy. It may ask about faith practice, parish or worship details, a child’s current school, a sibling connection or another school-specific criterion.
The extra form does not normally replace the main application through your home local authority. Treat them as two connected tasks and confirm exactly what the school and council require for the current admission year.
Read the admissions policy beside the form
Do not complete the form from memory or from advice given to another family. Open the school’s current admissions policy and use it to understand why each question is being asked, which category may apply and what evidence is accepted.
Pay attention to definitions. A policy may define sibling, home address, regular worship, looked-after status or membership of a faith community in a specific way.
- Check the form is for the correct school and admission year.
- Confirm whether it is completed online, emailed, posted or delivered.
- Identify who must sign or verify any section.
- Record the form deadline separately from the council deadline.
Build a small evidence pack
Gather evidence before starting the final form so names, dates and addresses stay consistent. Only provide documents the school requests, and avoid sending original documents unless the instructions specifically require them.
- Address evidence using the document types and dates the policy accepts.
- Faith, parish or worship evidence completed by the correct authorised person.
- Sibling details exactly as recorded by the school.
- Professional supporting evidence where a policy allows medical or social priority.
- A saved copy or photograph of every completed page and attachment.
Avoid the common submission mistakes
Most form problems are administrative rather than complicated. Families use an old form, miss a signature, assume the school receives information from the council or discover too late that a verifier was unavailable.
Review the form once for accuracy and once for completeness. Check names, addresses, dates, tick boxes, signatures and attachments before submitting.
A complete, on-time form is more valuable than a detailed form that misses the instructions.
Save proof and follow up carefully
After submitting, save the confirmation email, receipt, screenshot or postal evidence with the final form and attachments. Note the date, submission method and any reference number.
If confirmation does not arrive when the instructions say it should, contact the school’s admissions office calmly and keep a written record of the response. Do not wait until offer day to check whether a required form was received.
- Check whether the school wants a SIF or another supporting form.
- Collect proof of address, faith documents or other evidence early.
- Submit the form by the school’s deadline, not just the main deadline.
- Keep a copy of everything you send for your own records.
Keep the journey moving by comparing schools, checking deadlines and saving the guide that matches your route.
