In relation to changes to the schools guidance for January 2022 return, NAHT Cymru Director Laura Doel said: "The availability of staff is the biggest threat to education in January. Without the workforce fit and well, learners cannot go back to the classroom.

"If LFTs for close contacts need to be taken for 7 days there must be a supply available for schools. If track and trace are supposed to support the system we must ensure they have the capacity to do so and if parents are to understand what is required of them, there must be clear communication. All of these elements need to be up and running next week to ensure the return to school is the success we want it to be. The pressure on TTP system is an ongoing concern and therefore we maintain that classes should be designated as contact groups for testing purposes to bring consistency across all LA areas and relieve the added pressure to trace close contacts, particularly in primary schools which is extremely difficult.

"Given that staff availability has been a key area of concerns for months, NAHT Cymru believes prioritising the workforce for booster vaccinations was an opportunity missed. It is too early to tell whether the new measures announced will be enough to keep schools open in January but we welcome the reintroduction of staggered session times and the planning days that will help schools manage their local situations. Remote learning will remain a last resort, with staff absence and risk levels being the determining factors, but be assured that school leaders remain committed to doing all they can to support their learners and their families."
