## Maths Political News

The UK government has withdrawn £6m grant funding intended to establish a national academy for mathematical sciences. The official response on the original funding call says:

The Department for Science, Innovation and Technology (DSIT) has concluded this competition without awarding grant funding to support the establishment of a new National Academy focused on Mathematical Sciences.

The government recognises the essential, valuable contributions of the mathematical sciences in science, engineering, innovation and growth in the UK and will explore how best to provide support and promote mathematics without supporting the creation of a new National Academy focused on Mathematical Sciences.

The Maths Horizons Project, an independent rapid review of maths curriculum and assessment in England, has launched. According to their website,

The Maths Horizons Project will bring together a group of teachers and others experts to analyse options for maths curriculum and assessment. We will consult widely, including primary and secondary schools, colleges, universities and businesses.
