Issues involved in empowering evaluation conducted with grass-roots organizations are discussed. One major issue centers on conflicting evaluation standards evaluators and stakeholders may have, and another is whether there is harmony between the empowerment model's goals of evaluation ownership and group advocacy.

Y. S. Lincoln and E. G. Guba consider L. Sechrest's comments on their book "Fourth Generation Evaluation" as less a criticism than an attempt to demolish. D. M. Fetterman also objects to much of Sechrest's address. E. J. Posavac generally agrees with conclusions of Welch and Sternhagen. (SLD)

The formative/summative evaluation dichotomy suggested by M. Scriven is challenged, and a conceptual typology is presented that crosses improvement and assessment evaluation functions with process and outcome program stages for four basic types of evaluation. This framework accommodates mixed types of evaluations. (SLD)

The literature on evaluation of employee involvement (EI) programs is reviewed, and five evaluation models and other procedures to increase EI usefulness to organizations are discussed. Better designed studies should include some form of preevaluation and postevaluation measures and should use more than one evaluation model. (SLD)

Definitions of and approaches to naturalistic evaluation are discussed. The qualitative aspects of the discipline are reviewed; and use of naturalistic evaluation in descriptions, illustrations, explications, hypothesis testing, and assessment of public spending are defined. A new paradigm for naturalistic evaluation is proposed. (TJH)

A program evaluation approach is proposed that individualizes objectives based on participants' characteristics and needs. This approach reflects tailoring of program services and assessment within the parameters of the program in order to maximize participant performance. The model appears theoretically sound and practical, but it has not been…

A methodology for calculating the return on training investment is described. The method covers attitudes, knowledge, and behavior of participants as well as effectiveness in organizational improvement. Output, time savings, quality improvements, and "soft data" on effectiveness are set against costs. (TJH)

In spite of many inherent problems, impact evaluation should remain an integral part of program evaluation, both because impact evaluation brings its budget justification with it, and because its focus on causal hypotheses is an essential part of evaluation. Methodology based on the author's body of work is reviewed. (SLD)

The application of time series analysis is described, focusing on the use of regression analysis for analyzing time series in a way that may make it more readily available to an evaluation practice audience. Practical guidelines are suggested for decision makers in government, health, and social welfare agencies. (SLD)

This case study describes an unsuccessful research proposal submitted in response to a request for applications for projects to implement and evaluate up to 18 innovative programs for homeless persons with alcohol or other drug problems. This unsuccessful proposal reflects several tensions inherent in evaluation research. (SLD)
