Origin of the Terms

The terms “formative evaluation” and “summative evaluation” were first introduced by Michael Scriven, a prominent philosopher of science, in his book “The Methodology of Evaluation” published in 1967.

Scriven used the term “formative evaluation” to refer to evaluation activities that are conducted during the development process of a program or product, with the aim of improving its quality. The term “summative evaluation” was used to refer to the evaluation of the program or product at the end of the development process, with the aim of determining its overall effectiveness.

Since then, the terms have been widely used in various fields, including education, psychology, public health, and business, to describe the two types of evaluation methods.

Today, formative evaluation and summative evaluation are recognized as important components of the evaluation process, and they are used to assess the effectiveness of programs, products, or services and to inform decision-making.

What is the difference between Formative and Summative Evaluation?

Formative evaluation and summative evaluation are two types of evaluation methods used in various fields, including education, psychology, and business.

Formative evaluation is an ongoing process that involves collecting feedback and data during the development of a program, product, or service. The purpose of formative evaluation is to identify areas for improvement and make changes as needed to ensure that the final product or service meets the intended goals and objectives. Formative evaluation is usually conducted during the early stages of development and is often used to guide decision-making and improve the quality of the final product.

Summative evaluation, on the other hand, is conducted at the end of a program, product, or service to determine its effectiveness and success in achieving its goals and objectives. Summative evaluation is usually conducted using predetermined criteria and involves collecting data through surveys, tests, or other methods to measure the outcomes of the program. The purpose of summative evaluation is to provide feedback on the overall effectiveness of the program, product, or service and to inform decisions about its future.

Importance of Formative and Summative Evaluation in Program Development

Formative and summative evaluations play a crucial role in the development of effective programs. Here are some reasons why they are important:

1. Identify areas for improvement: Formative evaluation allows program developers to identify areas for improvement during the development process. This helps to ensure that the final program meets the intended goals and objectives and is of high quality.
2. Provide feedback: Both formative and summative evaluations provide feedback that can be used to improve the program. Formative evaluation provides ongoing feedback that can be used to make adjustments during the development process, while summative evaluation provides feedback on the overall success of the program.
3. Measure effectiveness: Summative evaluation measures the effectiveness of the program in achieving its intended goals and objectives. This information can be used to determine whether the program is successful and to inform decisions about its future.
4. Ensure accountability: Evaluation helps to ensure accountability by providing evidence of program outcomes. This information can be used to demonstrate program effectiveness to stakeholders and funders.
5. Improve decision-making: Evaluation provides data-driven information that can be used to inform decision-making. This helps to ensure that decisions are based on reliable and valid information, rather than assumptions or opinions.

Formative and summative evaluations are important for ensuring the success of programs. They provide feedback, measure effectiveness, ensure accountability, and improve decision-making.

Research Methods for Formative vs. Summative Evaluations

The research methods used for formative and summative evaluations differ depending on the goals of the evaluation.

Formative evaluation typically involves collecting qualitative data through methods such as focus groups, interviews, and observations. These methods allow evaluators to gather feedback from stakeholders in a more detailed and nuanced way than quantitative methods. Formative evaluation may also involve analyzing data from previous evaluations, conducting literature reviews, or using other secondary sources of data.

The purpose of formative evaluation is to identify areas for improvement and make changes to the program, product, or service during the development process. Therefore, the research methods used in formative evaluation are designed to provide information that can be used to guide decision-making and improve the quality of the final product.

Summative evaluation, on the other hand, typically involves collecting quantitative data through methods such as surveys, standardized tests, and other assessments. These methods allow evaluators to measure the overall success of the program, product, or service in achieving its goals and objectives. Summative evaluation may also involve analyzing data from previous evaluations or using other secondary sources of data.

The purpose of summative evaluation is to provide feedback on the effectiveness of the program, product, or service and to inform decisions about its future. Therefore, the research methods used in summative evaluation are designed to provide reliable and valid measures of program outcomes that can be used to make data-driven decisions.

In summary, formative evaluation typically involves qualitative research methods, while summative evaluation typically involves quantitative research methods. However, both types of evaluation may also incorporate a mix of research methods depending on the specific goals of the evaluation.

Examples of Formative and Summative Evaluation in Practice

Here are some examples of formative and summative evaluations in practice:

Formative Evaluation:

1. A school district develops a new curriculum and conducts formative evaluation by gathering feedback from teachers and students through surveys and focus groups. The feedback is used to make adjustments to the curriculum to ensure that it meets the needs of students and is effective in achieving its goals.
2. A nonprofit organization that provides mentoring services to at-risk youth conducts formative evaluation by conducting regular check-ins with mentors and mentees to gather feedback on the program. This feedback is used to make adjustments to the program to improve the quality of the mentoring experience for both mentors and mentees.

Summative Evaluation:

1. A public health organization implements a new community-based program to reduce obesity rates in a specific population. The organization conducts summative evaluation by collecting data on obesity rates before and after the program is implemented. The data is used to determine the effectiveness of the program in achieving its intended goal.
2. A business develops a new customer service training program for its employees. The business conducts summative evaluation by administering surveys to customers to gather feedback on their experience with customer service before and after the training program is implemented. The data is used to determine whether the training program is effective in improving customer satisfaction.

Challenges and Limitations of Formative and Summative Evaluation

While formative and summative evaluations are essential for ensuring the success of programs, they also present some challenges and limitations. Here are some examples:

Challenges of Formative Evaluation:

1. Time-consuming: Formative evaluation can be time-consuming, as it requires collecting and analyzing data throughout the development process.
2. Limited resources: Conducting formative evaluation may require additional resources, such as staff time or funding, which may not be readily available.
3. Subjectivity: Formative evaluation is often based on subjective feedback and may be influenced by individual perspectives or biases.
4. Difficulty in measuring outcomes: Formative evaluation may focus on inputs, processes, or outputs, which can make it difficult to measure outcomes.

Limitations of Summative Evaluation:

1. Lack of control: Summative evaluation may be limited by factors outside of the program’s control, such as external events or environmental factors.
2. Timing: The timing of summative evaluation can be challenging, as it may not provide immediate feedback that can be used to make adjustments during the program.
3. Cost: Summative evaluation can be costly, particularly if it involves administering standardized tests or other assessments.
