"Inclusion criteria" refers to that set of characteristics that all participants must exhibit so as to be included in the data collection procedure.
You will be required to describe particular characteristics that are required to be present in participants in the target group (e.g. particular age, cultural derivation, background, physical characteristics, disease status, etc.). Unless there are good reasons for the deception, inclusion criteria must be made available in writing at the point of recruitment. Make sure your inclusion criteria is well-defined, justifiable, and aligned with your study objectives.
"Exclusion criteria" refers to that set of characteristics that excludes individuals (i.e. those individuals who have been recruited and have indicated a willingness to participate) from participating.
Unless there are good reasons for the deception, exclusion criteria must be made available in writing at the point of recruitment. Make sure your exclusion criteria is well-defined, justifiable, and aligned with your study objectives.
