01General Scientific Knowledge and Aptitude
This paper checks whether you can apply school- and degree-level science across disciplines - physics, chemistry, biology and earth science - and handle numerical, verbal and logical reasoning quickly. Expect SI-unit handling, graph and table interpretation, basic stoichiometry, electricity and mechanics, cell biology and ecology, plus aptitude items on ratios, percentages and number series.
361 words, about 2 min02Discipline-Specific Scientific Subject Knowledge
The discipline paper is set at honours-degree level in the subject you applied under - chemistry, biology, physics, agriculture, geology and so on - but a common set of competencies decides many marks: selecting a valid method, calibrating it, running quality controls, and reporting results with correct units, dilution factors and uncertainty. A method is only valid within its validated range, matrix and detection limit; outside that range you dilute, concentrate or change method.
362 words, about 2 min03Scientific Research Methodology and Data Analysis
This domain tests experimental design (controls, randomisation, replication, blinding), measurement quality, the choice of statistical test, and the correct reading of p-values, confidence intervals and effect sizes. State hypotheses before seeing data; the null hypothesis asserts no difference or no association.
391 words, about 2 min04Scientific Administration, Policy and Ethics
This domain examines how publicly funded science is planned, procured, staffed and held to account, and the ethical and legal duties of a scientific officer in Sri Lanka's public service. Public expenditure must fall within the approved annual estimate and follow the Establishments Code for personnel matters, the Financial Regulations for financial control, and the national procurement guidelines for goods, works and services.
