A Terms of Reference (ToR) document provides an important overview of what is expected in an evaluation.MethodRequest for proposal (RFP)
A Request for Proposal (RFP) is a formal request for evaluators to prepare a response to a planned evaluation and are generally used to select the final evaluator for the evaluation.MethodExpression of interest
An expression of interest (EoI) is a way for an organisation to publish its intention to appoint an evaluation team to conduct an evaluation of a specific project or program.MethodScope of work
A Scope of Work (SOW) is a plan for conducting an evaluation which outlines the work that is to be performed by the evaluation team.MethodMemorandum of understanding
A Memorandum of Understanding (MOU) outlines an agreement between two collaborating bodies in order to identify the working relationships and guidelines that exist between them.MethodStatistical generalisation
Statistical generalisation involves statistically calculating the likely parameters of a population using data from a random sample of that population.MethodSequential sampling
Sequential sampling is a non-probabilistic sampling technique, in which the sample size, n, is not fixed in advanced, nor is the timeframe of data collection.MethodAnalytical generalisation
Analytical generalisation involves making projections about the likely transferability of findings from an evaluation, based on a theoretical analysis of the factors producing outcomes and the effect of context.MethodContractual agreement
A formal contract is needed to engage an external evaluator and a written agreement covering similar issues can also be used to document agreements about an internal evaluator.MethodRandomised control trials for the impact evaluation of development initiatives: a statistician's point of view
This paper from the Institutional Learning and Change (ILAC) Initiative provides a range of technical and practical reflections on the use of randomised control trials in impact evaluation.ResourceMulti-stage sampling
Multi-stage sampling represents a more complicated form of cluster sampling in which larger clusters are further subdivided into smaller, more targeted groupings for the purposes of surveying.MethodEvaluation journals
Evaluation journals play an important role in documenting, developing, and sharing theory and practice. They are an important component in strengthening evaluation capacity.MethodSimple random sampling
A simple random sample (SRS) is the most basic probabilistic method used for creating a sample from a population.MethodStratified random sampling
Stratified random sampling is a probabilistic sampling method, in which the first step is to split the population into strata, i.e. sections or segments.MethodQualitative research & evaluation methods: Integrating theory and practice
The fourth edition of Michael Quinn Patton's Qualitative Research & Evaluation Methods Integrating Theory and Practice, published by Sage Publications, analyses and provides clear guidance and advice for usiResource
