See the criteria overview for a general introduction to the quality criteria.
For definitions of the instrument characteristics, see the glossary.
Finally, four categories or types of instruments, and the psychometric analyses that are necessary for establishing the reliability and validity of each type, are described.
The quality criteria for sound project evaluation instruments are organized into three sections corresponding to the three principal characteristics of instruments: (1) Design, (2) Technical Quality, and (3) Utility.
The alignment table shows how glossary and criteria entries for instrument characteristics align to evaluation standards.
The development of data-gathering instruments should be based on a coherent set of activities that lead to the adoption and implementation of instruments that yield valid and reliable evidence of project effects.Project participants, members of the evaluation team, or other stakeholders may be the appropriate respondents for a specific data-gathering approach.In cases where it is not possible to involve all participants or stakeholders, random or purposeful sampling is called for.Each evaluation question implies appropriate scheduling of data gathering.Formative evaluation questions imply activity during and possibly preceding project implementation.
