High-profile law firm Mishcon de Reya has announced it is acting for a group of students and their parents in a challenge to this year’s International Baccalaureate results.

After this summer’s exams were cancelled, IB results were awarded via an algorithm that included historical data, coursework and teachers’ predictions. 

But the publication of the IB Diploma results in early July led to a wave of anger from students who were unhappy with how results had been awarded.

In a statement today, Mishcon de Reya said the method of awarding results used by the International Baccalaureate (known as the IB or IBO) ignored teachers’ predictions, which resulted in unfair outcomes.

The challenge, the law firm explained in a statement, will be based on data protection grounds.

Mishcon de Reya partner Adam Rose, who represents the students, said: “GDPR [General Data Protection Regulation] required the IBO to process our clients’ personal data fairly, accurately and in a transparent way - but on all counts they failed to do so.

“This year’s cohort of students have already had terrible disruption to their education from Covid, only to then been treated appallingly by the IBO.

“Instead of ensuring the fairest possible outcome for students, the IBO adopted an awarding model which may have been administratively convenient but which fails, in many cases, to recognise and reflect students’ academic ability.

“Our clients have suffered significant distress as a result of IBO’s conduct, and we are asking IBO to put this right, by reconsidering our clients’ cases and giving proper regard to teacher predictions.”

Mishcon de Reya has written to the International Baccalaureate.

So far, there are fewer than 10 students involved in the challenge but the firm expects the number to grow. 

The IB has been contacted for comment.
