Ofqual research suggests that, in maths, 4% of students receive a mark which does not align with the ‘definitive grade’ given by the principal examiners. Currently, a sample of only 1.2% of questions are double marked (Ofqual 2018, p. 9). Automarking software can significantly reduce that margin of error and improve consistency by augmenting and supporting the work done by examiners.
Our CEO (and former maths teacher) Rob Percival, said: “With so few questions double marked, there is a lot of scope for error. A system like Blutick can review 100% of marked papers and flag potentially erroneous responses for further checking.”
The Blutick trial used automated marking to assess 257 scripts across two GCSE exam papers. An examiner then reviewed the students’ responses and the Blutick mark and corrected the mark where necessary, returning an accuracy rate of 98.6% to 98.75% by the AI software.
More automation in marking processes is a growing focus for exam boards and for Ofqual. Automarking software like Blutick provides a potential solution.
