Commenting on the most recent school attendance data released by the government today, Paul Whiteman, general secretary of school leaders’ union NAHT, said: “These numbers reflect the latest changes to government policy, which require far fewer pupils to self-isolate when there is a positive case identified in school.  

“However, it’s important to note that these national figures mask some significant issues arising at a local level, and we already know of schools that are struggling to keep classes open due to outbreaks occurring.

“It is crucial that both central and local government are now on high alert and are ready to react quickly if and when cases rise rapidly or outbreaks occur. The next few weeks will be crucial.”
