How do I ensure my evaluation is credible?

Demonstrating your understanding of ethical good practice will, in itself, go a long way to delivering a trustworthy evaluation. You also demonstrate your credibility through use of a well-designed evaluation: one that uses appropriate methods and tools, does not gather information that is not used, and which does not place unnecessary burdens on your participants. In addition it is important to demonstrate that you have considered and attempted to avoid bias wherever possible.
