The Irish Times is reporting that 38 student are suspected of cheating in this year's Leaving Certificate examinations.
The State Examination Commission (SEC) has withheld the Leaving Cert results of these students while the results of a further 34 students are being 'provisionally' withheld while an investigation is carried out.
Sources within the SEC say that the rise of smartphones and social media has made cheating more tempting to students.
In previous years, suspicions of cheating have been detected through similar work from more than one candidate while correcting work from the same centre.
Some examiners have also previously discovered notes or paper brought in by students in the exam scripts.
