Accuracy: The extent to which an evaluation is truthful or valid in what it says about a program, project, or material.
Achievement: Performance as determined by some type of assessment or testing.
Affective: Consists of emotions, feelings, and attitudes.
Anonymity (provision for): Evaluator action to ensure that the identity of subjects cannot be ascertained during the course of a study, in study reports, or in any other way.
Assessment: Often used as a synonym for evaluation. The term is sometimes recommended for restriction to processes that are focused on quantitative and/or testing approaches.
Attitude: A person's opinion about another person, thing, or state.
Attrition: Loss of subjects from the defined sample during the course of data collection.
Audience(s): Consumers of the evaluation; those who will or should read or hear of the evaluation, either during or at the end of the evaluation process. Includes those persons who will be guided by the evaluation in making decisions and all others who have a stake in the evaluation (see stakeholders).
Authentic assessment: Alternative to traditional testing that focuses on student skill in carrying out realworld tasks.
Background: Information that describes the project, including its goals, objectives, context, and stakeholders.
Baseline: Facts about the condition or performance of subjects prior to treatment or intervention.
Behavioral objectives: Measurable changes in behavior that are targeted by a project.

Case study: An intensive, detailed description and analysis of a single project, program, or instructional material in the context of its environment.
Categorical scale: A scale that distinguishes among individuals by putting them into a limited number of groups or categories.
Checklist approach: The principal instrument for practical evaluation, especially for investigating the thoroughness of implementation.
Client: The person or group or agency that commissioned the evaluation.
Coding: To translate a given set of data or items into descriptive or analytic categories to be used for data labeling and retrieval.
Cohort: A term used to designate one group among many in a study. For example, "the first cohort" may be the first group to have participated in a training program.
Component: A physically or temporally discrete part of a whole. It is any segment that can be combined with others to make a whole.
Conceptual scheme: A set of concepts that generate hypotheses and simplify description, through the classification and categorization of phenomena, and the identification of relationships among them.
Conclusions (of an evaluation): Final judgments and recommendations.
Content analysis: A process using a parsimonious classification system to determine the characteristics of a body of material or practices.
Context (of an evaluation): The combination of factors accompanying the study that may have influenced its results, including geographic location, timing, political and social climate, economic conditions, and other relevant professional activities in progress at the same time.
Continuous scale: A scale containing a large, perhaps infinite, number of intervals. Units on a continuous scale do not have a minimum size but rather can be broken down into smaller and smaller parts. For example, grade point average (GPA) is measured on a continuous scale, a student can have a GPA or 3, 3.5, 3.51, etc. (See categorical scale.)
Criterion, criteria: A criterion (variable) is whatever is used to measure a successful or unsuccessful outcome, e.g., grade point average.
Criterion-referenced tes: Test whose scores are interpreted by referral to well-defined domains of content or behaviors, rather than by referral to the performance of some comparable group of people.
Cross-case analysis: Grouping data from different persons to common questions or analyzing different perspectives on issues under study.
Cross-sectional study: A cross-section is a random sample of a population, and a cross-sectional study examines this sample at one point in time. Successive cross-sectional studies can be used as a substitute for a longitudinal study. For example, examining today's first-year students and today's graduating seniors may enable the evaluator to infer that the college experience has produced or can be expected to accompany the difference between them. The cross-sectional study substitutes today's seniors for a population that cannot be studied until four years later.
Data display: A compact form of organizing the available information (for example, graphs, charts, matrices).

Dissemination: The process of communicating information to specific audiences for the purpose of extending knowledge and, in some cases, with a view to modifying policies and practices.
Document: Any written or recorded material not specifically prepared for the evaluation.
Effectiveness: Refers to the worth of a project in achieving formative or summative objectives. "Success" is its rough equivalent.
Elite interviewers: Well-qualified and especially trained persons who can successfully interact with highlevel interviewees and are knowledgeable about the issues included in the evaluation.
Ethnography: Descriptive anthropology. Ethnographic program evaluation methods often focus on a program's culture.
Executive summary: A nontechnical summary statement designed to provide a quick overview of the full-length report on which it is based.
External evaluation: Evaluation conducted by an evaluator outside the organization within which the project is housed.
Field notes: Observer's detailed description of what has been observed.
Focus group: A group selected for its relevance to an evaluation that is engaged by a trained facilitator in a series of discussions designed for sharing insights, ideas, and observations on a topic of concern to the evaluation.
Formative evaluation: Evaluation designed and used to improve an intervention, especially when it is still being developed.
Goal: A broad-based description of an intended outcome.
Hypothesis testing: The standard model of the classical approach to scientific research in which a hypothesis is formulated before the experiment to test its truth.
Impact evaluation: An evaluation focused on outcomes or payoff of a project.
Implementation evaluation: Assessing program delivery (a subset of formative evaluation).
In-depth interview: A guided conversation between a skilled interviewer and an interviewee that seeks to maximize opportunities for the expression of a respondent's feelings and ideas through the use of open-ended questions and a loosely structured interview guide.
Informed consent: Agreement by the participants in an evaluation to the use, in specified ways for stated purposes, of their names and/or confidential information they supplied.
Instrument: An assessment device (test, questionnaire, protocol, etc.) adopted, adapted, or constructed for the purpose of the evaluation.
Internal evaluator: A staff member or unit from the organization within which the project is housed.
Inter-rater reliability: A measure of the extent to which different raters score an event or response in the same way.
Intervention: Project feature or innovation subject to evaluation.
Intra-case analysis: Writing a case study for each person or unit studied.
Key informant: Person with background, knowledge, or special skills relevant to topics examined by the evaluation.
Longitudinal study: An investigation or study in which a particular individual or group of individuals is followed over a substantial period of time to discover changes that may be attributable to the influence of the treatment, or to maturation, or the environment. (See also cross-sectional study.)
Matrix: An arrangement of rows and columns used to display multidimensional information.
Measurement: Determination of the magnitude of a quantity.
Meta-evaluation: Evaluation of the merit of the evaluation itself.
