IB-required assessment

All IB Diploma courses include summative assessments that measure what students know and can do. One of these is internal, meaning that it is set, delivered, and marked by the instructor. The other is external, meaning that the student's work is forwarded to an IB examiner for marking.

Students enrolled in Theory of Knowledge must complete two such assessments for the IB:

• The Presentation (internal). Worth 33% of the overall TOK grade. 
• The Essay (external). Work 67% of the overall TOK grade.

The points earned for these two assessments are added together to produce the overall mark (A-E) that the student receives for TOK. The mark earned in TOK, combined with the mark for the Extended Essay, can add up to 3 bonus points to the student's total needed to earn the IB Diploma.  

IB Assessment on Report Cards: The "IBO Mark"

Unlike other IB courses that use 7 (high) through 1 (low) as marks, TOK uses A (high) through E (low). At each grade reporting period, beginning with quarter 1, students will find an IBO mark on their report card. This mark reflects how well students are doing on summative (major) assessments that use formal IB assessment criteria. It does not include homework or formative (minor) assessments. The purpose of these marks is to allow parents and students to keep track of progress towards meeting IB objectives. This mark is not "official" in that it does not become part of any official transcript.

The IBO mark for the first semester is a combination of the (best) Essay and the Presentation (Internal Assessment). The Essay is approximately twice the weight of the Presentation. There is some correlation between the final semester class grade and the IBO mark, but generally speaking IBO marks are lower because they include only IB-aligned summative assessments, while the final semester grade includes homework, revisions, and other minor assignments.
