Manuals and Guidelines

Test sessions have to be administered in a standardized way across the participating countries, schools, or other educational institutions involved. Study manuals ensure all involved are well informed about the correct methods and protocols.

We are able to ensure that these materials include sound information and advice on, among other matters, sampling, preparation of instruments, field operations, data collection, and data cleaning and verification.

Our services relating to designing and developing manuals and guidelines encompass:

  • Manuals for the agents involved in international studies
  • Manuals for the coordinators in the institutions
  • Handbooks and training papers for test administrators.
