A crisis-hit Birmingham school has advertised for a new head teacher, just weeks after pupils pelted staff with eggs in a row over school uniforms.

Castle Vale Performing Arts College has advertised for a new principal, a month after embattled head Charlotte Blencowe took over at the school.

She now faces reapplying for the role if she wishes to remain at the school.

Ms Blencowe came under fire from parents last month when dozens of pupils were barred from lessons for not wearing the right shoes on the first day of term, sparking angry protests.

The Academies Enterprise Trust (AET), which placed the advert, insisted that Miss Blencowe’s appointment last summer was not a permanent one.

An advisor to Ms Blencowe said she was currently considering whether to apply for the permanent role, and insisted that the school – set to become an academy next year – was improving.

An AET spokesman said: “Charlotte Blencowe was placed in the position as head teacher by the governing body and Birmingham City Council as an employee of the Academies Enterprise Trust.

“The intention was that the position was for approximately a year to provide stability at the school following the departure of the previous head.

“The Department for Education contacted AET asking that the position be advertised on a permanent basis.”

Ms Blencowe took over as head at Castle Vale when previous head Clive Owen quit at the end of the summer term.

Her headship got off to a rocky start when crowds of parents and pupils gathered outside the gates over the tough new uniform code on September 6.

Police were also called after staff were hit with eggs during the protest.

New rules imposed at the school saw children being handed “tinkle cards” – written in childish scrawl and to be used just once a week – to hold up if they needed the toilet. It stated: “I am missing a super important learning opportunity because I need a tinkle.”
