Students from the school submitted an application with written and video sources as well as going through an assessment process where they participated in the renovation of a playground and facilities at Foulds Primary School in Barnet.
Kevin Prunty, executive headteacher, said: “Cranford Community College has been working with, advising and learning from schools, universities and education networks in the highest performing education systems around the globe for many years, including Finland, Singapore, Hong Kong, Korea and China, and we are truly delighted that our students have benefited to such a degree that their skills have been rated so highly against international standards.”
The award recognises state secondary schools which have gone beyond outstanding, and are exceptional, compared to international standards, with students of a high calibre and world class qualities.
Co-director of the WCSQM, Miranda Perry, said: "This is a fantastic achievement by both schools, and we're really proud to confirm their world class status.
"Cranford Community College and The Heathland School are two of only 26 schools in the country to have qualified for the final stage of the assessment process, and we look forward to working with them in the coming years."
These schools' achievements will be celebrated at the annual World Class School awards ceremony in November, where they will both officially receive the quality mark.
