Assessment

All IB subjects are assessed but not in the same way. Generally speaking, all IB subjects have assessments that will measure attainment in a variety of ways, and many subjects have written examinations.

Simply put, there are two categories of assessment:

Internal assessments or IAs

Internal assessments may take the form of an essay or written task (e.g.,English A1 World Literature, Languages A2), portfolio or record of tasks (Experimental Sciences, Math HL or Math SL), recorded orals (Languages A1, A2, B and ab inito) or performance (Theatre Arts, Dance) or project (Math Studies, Computer Science)

These assessment tasks are completed during the course of study and students are given a number of days or weeks to complete them. The completed tasks are graded by the ISB teacher using a published IB rubric. This rubric will have been discussed with, and used by, students prior to the start of the work.

The grades of the teachers are submitted to the IB office along with a number of samples of work and these samples are graded by an IB examiner, along with samples from other IB schools, using the same rubric. The result of this second grading determines the final IA scores. Final IA scores are not reported by IB prior to the written examinations.

In general, internal assessments may contribute up to 30% of the final IB score.

External assessments

With the exception of the written examinations, some external assessments may take the same or similar forms to the internal assessments, however, this work is not graded by the teacher. All external assessments are graded by IB examiners using published rubrics. As with the internal assessments the rubrics are discussed and used in class prior to the students starting the work.

Written examinations are taken in accordance with a published schedule and regulations to maintain the integrity of the examinations and results. The schedule applies to all schools taking examinations and cannot be changed by the school. There are no make ups for these examinations.

The completed examination papers are sent to IB examiners for grading.

In general, external assessments contribute up to 70% of the final IB score.

IB scoring

IB subject examinations are awarded grades on a seven-point scale:

7     Excellent
6     Very good
5     Good
4     Satisfactory
3     Mediocre
2     Poor
1     Very poor

Theory of Knowledge and the Extended Essay are awarded grades on an A – E system:

A Excellent; B Good; C Satisfactory; D Mediocre; E Elementary

To earn the IB Diploma, a candidate must normally have at least a 4 in each of the six subjects studied, with a total points of at least 24. Any student who does not complete the requirements of CAS or receives an E in Theory of Knowledge or Extended Essay and less than 28 points from the subject areas will be ineligible for the award of the Diploma.
A student who does not complete the full diploma will be awarded certificates in individual subjects.

Results

The IB examination office reports the final IB scores in early July. Students are given PIN codes to access their scores before the end of the school year.
