Grading, assessment, and knowing[1]

Introduction[edit]

The assessment component is broken into two parts: external and internal assessment. The external assessment is 70% of your grade, and the Internal assessment is 30% of your grade. The total time for external assessment is 2 hours and 30 minutes. The total time for internal assessment is 40 hours. The material on this page is used from the IB Computer Science Subject Guide[2].

External assessment (2 hours 30 minutes)[edit]

Paper 1[edit]

1 hour 30 minutes is allocated for an examination paper consisting of two compulsory sections:

  • Section A (30 minutes approximately) consists of several compulsory short answer questions. The maximum mark for this section is 25.
  • Section B (60 minutes approximately) consists of three compulsory structured questions. The maximum mark for this section is 45.

You can earn a maximum of 70 marks for paper 1. It is weighted for 45% of your final grade.

Paper 2[edit]

1 hour is allocated for paper 2 which is an examination paper linked to the option studied (which is web science).

  • The paper consists of between two and five compulsory questions. (45 marks)

You can earn a maximum of 45 marks for paper 2. It is weighted for 25% of your final grade.

Calculators: The use of calculators is not permitted in any computer science examination.

Internal assessment (40 hours)[edit]

This component is internally assessed by the teacher and externally moderated by the IB at the end of the course.

Solution[edit]

30 hours are allocated for the solution.

The development of a computational solution. Students must produce:

  • a cover page that follows the prescribed format
  • a product
  • supporting documentation (word limit 2,000 words).

You can earn a maximum of 34 marks for your solution.

Group 4 project[edit]

The group 4 project is a collaborative activity where students from different group 4 subjects work together on a scientific or technological topic, allowing for concepts and perceptions from across the disciplines to be shared. This is to encourage an understanding of the relationships between scientific disciplines and the overarching nature of the scientific method. The project can be practically or theoretically based. Collaboration between schools in different regions is encouraged.

Personal skills rubric

The group 4 project allows students to appreciate the environmental, social and ethical implications of science and technology. It may also allow them to understand the limitations of scientific study, for example, the shortage of appropriate data and/or the lack of resources. The emphasis is on interdisciplinary cooperation and the processes involved in scientific investigation, rather than the products of such investigation. 10 hours are allocated for group 4 project.

To be assessed using the criterion personal skills .


You can earn a total of 6 marks.
