More lessons are being suspended at Castle Rushen High School this week due to "significant staff shortages".
Some pupils are being asked to stay at home on certain days this week- some year groups will miss full days while others will miss specific lessons.
The problem, due to staff illness and isolation, was highlighted in a letter to parents last week.
Headteacher Keith Winstanley said updates will be given throughout the week.
The school letter, dated 3 December, can be seen here.
