What is it? Why is it important?

It is essential to guarantee that study data is collected and documented according to specifications given in the study protocol. In addition, compliance to study relevant SOPs and WIs addressing DM procedures ensure data of high quality.

Staff should be trained based on:

  • Means by which source data is collected (e.g. correct blood sampling and processing)
  • Collection of raw data (e.g. knowledge regarding correct data source)
  • Data entry procedures into the study database
  • Ongoing data quality checks and monitoring


In the event that participants are asked to enter data in a CRF, be it paper or electronic, they should receive appropriate training on how to do so. Both compliance as well as data quality is directly related to how well participant were trained on data collection and documentation procedures.

What do I need to do?

Train study staff on:

  • Defined DM SOPs/WIs and applicable guidelines before performing any DM delegated tasks
  • Implemented risk control measures needed to protect ongoing data quality

Ensure training is current and up to date (e.g. new staff, shift in delegated responsibilities, changes / updates in DM procedures or risk control measures)

For more information refer to Quality and Risk and Monitoring in this Trial Guide.


Training should be done:

  • Prior to performing study delegated tasks
  • By a qualified trainer or if manageable through self-training
  • Either on-site, face-to-face, by telephone or other applicable mean
  • During study initiation and repeated during study conduct especially in the event of poor compliance
  • Whenever necessary and before changes to study conduct (e.g. novel staff, major changes of CDMS)

Both trainer and trainee date and sign the training log. By signing, the trainee confirms with his/her signature to have read and understood its content.

On the training log always refer to type of documents trained (e.g. SOPs, guidelines). Include document name, date, and version number.
