A teaching crisis has forced Angus to draft in college lecturers to plug some of the subject gaps.
Angus Council’s head of schools and learning said although the shortage may be regarded as negative, the joint approach is “further enhancing relationships” between head teachers and Dundee and Angus College.
Some pupils are also being forced to travel to neighbouring schools to pursue their chosen subjects, which was described as a “make do and mend approach”.
North East Scotland Lib Dem MSP Mike Rumbles said: “It seems that Angus Council is trying hard to overcome the teacher shortages it faces.
“However, students moving between schools and having classes covered by college lecturers who are by definition focused on adult education, is not a satisfactory situation.
“The solution is to have a radical uplift in the terms and conditions of our teachers in order to attract more people to the profession.
“This make do and mend approach is a short term solution and it cannot go on for much longer without badly affecting the educational outcomes for our school students.
“The continuity of the educational experience is extremely important and if our students don’t know who their teachers are from one session to the next it cannot put anything other than more pressure on them.
“Even more unwanted pressure is added if our youngsters have to make arrangements to attend different schools at different times.
“We must remember that the educational experience of our youngsters can affect their whole future.
“We owe it to them to get this issue sorted out and get it sorted soon.”
Dr Pauline Stephen, director of schools and learning, made the admission about how they plug gaps in a response to a Scottish Parliament inquiry into subject choices.
As well as contacting head teachers, local authorities and higher education institutions, the committee is undertaking engagement work with pupils, parents, teachers and the Scottish Youth Parliament.
Dr Stephen said Angus schools work hard to ensure that a full range of subjects can be offered to learners.
She said all eight secondary schools use a similar curriculum structure and this has been negotiated and agreed with Dundee and Angus College “to ensure alignment to courses offered in partnership with further education”.
“Where courses have not been offered due to staff shortage all efforts have been made to accommodate young people in neighbouring schools where possible,” she said.
“This has meant a teacher from another school travelling to the school without the subject specialist to deliver the course.
“There are also examples of lecturers from Dundee and Angus College assisting with delivery due to teacher shortage.
“The result is that, although having the staff shortage may be regarded as negative, the joint solution focused approach is further enhancing relationships between our head teachers and Dundee and Angus College.”
