  • The International Baccalaureate (IB) Diploma Programme (DP) is an educational programme examined in one of three languages (English, French or Spanish) and is a leading university entrance course. Through this program students can obtain university course credits while attending high school. The program is recognized by all major universities in the world.
  • It is taught in 2,075 schools, often in international schools, in 125 countries all around the world. More than half of the schools offering the Diploma Programme are state funded schools.
  • Students elect six subjects of which they must study three at higher and three at standard levels. After a two year course they are examined by a mixture of externally set examination papers and internally assessed (externally moderated) coursework.
  • They are given a final grade out of 7 for each subject making a mark out of 42. To this mark is added a further possible three points representing their achievement in the Theory of Knowledge and Extended essays (externally assessed).
  • A student attaining 24 or more marks will be awarded the International Baccalaureate Diploma provided that he/she has attained grade levels of 4 or above in the higher subjects. There are a number of failing conditions which will prevent a student from being awarded a Diploma regardless of the points they received (such as non-completion of CAS, plagiarism, no EE etc).

    General objectives relating to Group IV (sciences)
  • The (assessment) objectives reflect those parts of the aims which will be assessed. Wherever appropriate the assessment will draw upon environmental and technological contexts; identify the social and economic effects of the experimental sciences, and the moral considerations of scientific activity.

    It is the intention of all experimental sciences programmes that students should be able to:

    Demonstrate: an understanding of scientific facts and concepts scientific methods/techniques scientific terminology methods of presenting scientific information

    Apply and use:
    • scientific facts and concepts
    • scientific methods/techniques
    • scientific terminology to communicate effectively
    • appropriate methods to present scientific information

    Construct, Analyse and Evaluate:-
    • hypotheses, research questions and predictions
    • scientific methods/techniques and procedures
    • scientific explanations

    Demonstrate: the personal skills of cooperation, perseverance and responsibility appropriate for effective scientific investigation and problem solving

    Demonstrate: the manipulative skills necessary to carry out scientific investigation with precision and safety.

    • Analyse: Classify the component parts and patterns.
    • Evaluate: Discuss and examine the implications and limitations.
    • Results: Raw data or manipulated data.
    • Scientific techniques: Qualitative/quantitative experimental 
      methods.
    • Data: Information that could include qualitative and/or quantitative 
      observations.
    • Scientific terminology: Use of correct nomenclature, conventions,
       units
      and significant figures.
    • Methods of presenting: written, oral, audio-visual, graphic and 
      using IT.
    • Scientific explanations: Explanations based on scientific 
      information.
    • Scientific investigation: Study of a phenomenon, hypothesis or
      theory.
    • Problem solving: Use of experimental data to solve a problem.
    • Hypothesis: An idea suggested as a possible way of explaining
      observations and phenomena.

    Glossary of terms relating to the assessment objectives

    • Demonstrate an understanding
    • Recall information (facts, concepts, models, data);
    • Translate information from one form to another;
    • Explain information; summarise information. Apply and use
    • Take given information and use it to solve a task.
    • Construct and Assemble scientific information in a logical
      manner.
