Making constant changes to the country's exam system can have a detrimental effect, says exam watchdog Ofqual, reports the BBC.
According to the body, the introduction of new Diplomas has been a positive move and recent changes to GCSE science exams were necessary, but the possibility of major changes could result in exam boards deciding not to take up new assessments.
Kathleen Tattersall, chief regulator of Ofqual, said England has a long history of failed qualification initiatives due to the sustained perception of vocational studies having a lower value than more traditional subjects.
Ms Tattersall told the BBC: "We must build in flexibility, enabling learners to update their skills and reaffirm their competences with qualifications that keep up to date."
She went on to say that Diplomas should be simplified in the coming years to encourage more pupils to undertake them.
