Examination

Junior Cycle Maths is assessed through a two-hour exam at the end of Third Year. There will be the option of sitting the Higher or Ordinary level version of this exam. This decision is usually made with consultation with a student’s teacher throughout the Junior Cycle course.

Classroom-based Assessments (CBAs)

Two CBAs are conducted in Junior Cycle maths. The teacher assesses the quality of work completed by the student and assigns a descriptor – Exceptional, Above Expectations, In Line with Expectations or Yet to Meet Expectations.

CBA1 (Mathematical Investigation) takes place in Second Year over the course of three weeks, during which students must identify a real world problem in their lives and use their mathematical knowledge to solve this.

CBA2 (Statistical Investigation) takes place in Third Year over the course of three weeks, during which students must conduct a statistical investigation and report on some topic which is of interest to them.
