How the GCA framework’s 12-week rule saves schools money

Managing a school budget often requires making difficult choices, especially when trying to balance operational efficiency with excellent student outcomes. Recruitment costs remain a significant pressure point for school business managers and headteachers across the UK. Finding the right permanent staff can be expensive, and temporary supply cover adds another layer of financial complexity.

One of the quietly useful features of the Government Commercial Agency (GCA) RM6376 framework is a provision specifically designed to help schools reduce recruitment costs. The framework includes a rule that lets schools convert a supply teacher into a permanent member of staff at no additional cost, provided a defined period of work has been completed.

Often referred to as the temp-to-perm rule or the 12-week rule, this framework feature is highly beneficial for school leaders. Understanding exactly how this mechanism works can save your school several thousand pounds on a single hire. It empowers you to build reliable, long-term teaching teams while maintaining strict compliance with procurement standards.

This guide explains the details of the 12-week rule, demonstrates the potential cost savings, and walks you through a practical example of a compliant transfer.

The rule in plain terms

When you book a worker through a GCA framework supplier, you have the option to take them on permanently without paying a placement fee. To access this benefit, your school simply needs to meet two clear conditions:

• The worker must have completed at least 12 weeks of work with your school on framework terms
• You must give the supplier at least 4 weeks’ written notice of the transfer

Once these two straightforward requirements are fulfilled, the permanent placement fee is waived completely. There are no transfer charges and no hidden costs to worry about. The worker seamlessly transitions from being engaged through the supplier to being a direct, permanent employee of your school or trust.

Financial impact

Outside of a compliant framework, recruitment agencies typically charge a permanent placement fee when a school directly hires a worker the agency originally provided. These fees vary widely depending on the agency, but for a teaching placement, they regularly sit between 15% and 25% of the worker’s annual salary.

For a teacher earning £35,000, a standard agency fee would cost your school roughly £5,000 to £8,750. This represents a substantial sum for a single hire, quickly depleting valuable budget reserves that could otherwise be spent on resources to enhance student outcomes.

Inside the GCA RM6376 framework, that placement fee drops to zero after the 12-week qualifying period. Many schools use supply work to trial a teacher, ensuring they are a perfect fit for the school community before offering a permanent post. If you regularly convert supply staff to permanent roles, the savings compound rapidly. Converting just two or three hires a year under this rule can mean avoiding £10,000 to £25,000 in placement fees entirely.

How the qualifying period works

The 12-week requirement does not mean 12 consecutive calendar weeks. Instead, it requires 12 weeks of actual work performed under the framework with your school. This distinction is incredibly important for part-time workers and varying supply patterns.

Different patterns count

The framework counts working days against the threshold, rather than calendar weeks. For instance, a worker who covers two days a week for 30 weeks has accumulated more than 12 full weeks of work, meaning they qualify for a free transfer. A worker who has completed five days a week for only three weeks has not yet met the threshold.

It must be on framework terms

The 12-week count exclusively applies to work performed under the GCA framework. If you have previously used the same worker through a non-framework arrangement, those prior weeks do not count toward the framework’s threshold. The clock officially starts the moment the worker is first engaged through a framework supplier on framework terms.

Both temporary and fixed-term work count

The rule applies flexibly to different types of engagement. Both day-to-day supply cover and longer fixed-term placements count toward the 12-week total, provided they are booked on framework terms. A teacher engaged on a one-term fixed-term framework contract will naturally pass the 12-week threshold during the course of that contract.

The 4-week notice period explained

Once you decide you want to convert the worker permanently, you must provide the supplier with 4 weeks’ written notice. This notice period serves a practical purpose: it gives the supplier adequate time to plan around losing the worker from their roster and manage any future bookings the worker may have had scheduled with other clients.

During these 4 weeks, the worker continues to operate on framework terms with your school. You simply continue to pay the standard framework invoices for the work they perform during the notice period. At the end of the 4 weeks, the worker becomes your direct employee. Any subsequent work they perform is then governed entirely by your school’s employment contract, rather than by the supplier or the framework.

A worked example of a compliant transfer

To illustrate how this works in practice, consider a supply teacher booked with a primary school on a framework arrangement starting in September. They cover classes three days a week for the autumn term. The school is highly impressed by their teaching standards and asks if they would consider a permanent role starting in January.

By the end of October, assuming they have worked 8 weeks of three days each, they have completed 24 working days. This equates to just under 5 working weeks, meaning they have not yet hit the 12-week threshold.

By the end of the autumn term, they have worked roughly 12 weeks of three days each. This totals about 36 working days, placing them comfortably over the 12 working weeks required. They now qualify for the free transfer.

In late November, the school issues the supplier with 4 weeks’ written notice of the transfer, naming the 1st of January as the start date for the permanent role.

From the 1st of January onward, the teacher operates as a direct employee of the school. The school pays absolutely no placement fee. The result is a highly successful hire: the school saves thousands of pounds, the teacher secures a permanent role they love, and the supplier is fairly compensated for the work performed up to the transfer date.

Common questions about temp-to-perm transfers

Does the worker have to want the permanent role?

Yes, absolutely. The framework cannot force a worker into permanent employment against their wishes. The 12-week rule simply dictates that if both the school and the worker mutually desire a permanent contract, the framework does not financially penalise the school for making that happen. The worker must accept your job offer through your standard recruitment process.

What if I don’t give 4 weeks’ notice?

If you transfer a worker to a permanent contract without supplying the required 4 weeks’ notice, the supplier may be entitled to a reduced fee or compensation under the framework’s terms. In reality, this rarely causes issues. Most schools are perfectly happy to give 4 weeks’ notice once a decision is made, as the worker is already in post and continues teaching during that time.

Does this apply to nominated workers too?

Yes, the 12-week rule applies to all workers engaged through the framework, including your nominated workers. After 12 weeks of work and the standard 4 weeks’ notice, you can transfer them to a permanent contract at no additional fee.

What about workers I’ve used both inside and outside the framework?

The 12-week count starts from the very first day of framework work. If you previously engaged the worker outside the framework, for example, through an older, non-compliant arrangement that is being migrated, the prior work does not count toward the threshold.

Can the supplier refuse to transfer the worker?

No, as long as the conditions are met. The framework’s standard terms strictly entitle you to make the transfer free of charge after 12 weeks of work and 4 weeks’ notice. The supplier’s responsibility is to handle the administrative side of the transfer efficiently, not to block your hiring process.

Transform your recruitment strategy with Engage Education

The temp-to-perm rule might not be the most heavily advertised feature of the GCA framework, but it is one of the most financially significant for school leaders. By effectively using this rule a few times a year, you can materially reduce the total cost of permanent recruitment at your school.

This approach also encourages you and your prospective staff to take the time needed to ensure a genuine fit. Rather than committing to a permanent contract on day one, both parties have 12 weeks to decide whether the placement works. When it does, the framework removes the financial barriers to making it permanent, driving operational efficiency and supporting better student outcomes.
