The Five Purposes of Assessment and Examples of Each

Assessment is an integral part of the educational process. It serves as a tool for gauging student learning and aiding in instructional decisions. There are five primary purposes of assessment: diagnostic, formative, summative, evaluative, and placement. Below we will briefly describe each purpose and provide examples to illustrate how they serve in real-life scenarios.

Diagnostic Assessment:

Purpose: Diagnostic assessment is conducted to identify students’ prior knowledge, strengths, and areas that need improvement. It helps educators design lessons that meet students’ needs effectively.

Theoretical Background: Diagnostic assessments are grounded in educational psychology and the concept of “prior knowledge.” They aim to identify a learner’s existing skills and knowledge before instruction begins. The theory behind this is that understanding a student’s starting point can help educators tailor their teaching methods to individual needs, aligning with the principles of differentiated instruction.

Example: Before beginning a unit on fractions, a math teacher administers a pre-test to evaluate students’ existing understanding of the concept. Based on the results, the teacher adjusts the lesson plan to focus on the areas where students struggled, ensuring that they have the foundational knowledge necessary for mastering fractions.

Formative Assessment:

Purpose: Formative assessment is an ongoing process used to monitor student learning during instruction. It provides feedback to both students and teachers, which can be used to make immediate adjustments to teaching and learning strategies.

Theoretical Background: Formative assessments are rooted in constructivist theories of learning, which emphasize the importance of active engagement and feedback in the learning process. The theory posits that learning is an ongoing process, and immediate feedback can help both teachers and students make necessary adjustments to teaching and learning strategies.

Example: In a science class, students are asked to complete a short quiz at the end of each week during a unit on photosynthesis. The teacher reviews the quizzes and realizes that students are struggling with the concept of chlorophyll. The teacher then allocates extra class time to clarify this concept and provides additional resources for students.

Summative Assessment:

Purpose: Summative assessment evaluates student learning at the conclusion of an instructional period. It aims to determine if students have achieved mastery of the content and is often used for assigning grades.

Theoretical Background: The theoretical foundation of summative assessments is often traced back to behaviorist theories of learning, which focus on observable and measurable outcomes. Summative assessments aim to evaluate whether students have achieved specific learning objectives, and they are often high-stakes, used for grading or determining advancement.

Example: At the end of the school year, students in a history class take a final exam that covers all the material they have learned throughout the year. This exam evaluates the students’ comprehensive understanding of the subject matter and contributes to their final grade.

Evaluative Assessment:

Purpose: Evaluative assessment is used to judge the effectiveness of a program, course, or instructional approach. It helps educators and stakeholders determine if learning objectives are being met and if changes are needed.

Theoretical Background: Evaluative assessments are closely related to program evaluation theories, which are often rooted in systems theory. The primary aim is to assess the effectiveness of an educational program, course, or method. These assessments provide data that can be used for decision-making and future planning, often involving multiple stakeholders.

Example: A school district implements a new reading program for elementary students. At the end of the year, standardized test scores are analyzed to determine if students’ reading skills have improved compared to previous years. This information is used to evaluate the effectiveness of the new program and to decide whether it should be continued or modified.

Placement Assessment:

Purpose: Placement assessment is used to determine the most appropriate educational setting or level for a student based on their skills and abilities.

Theoretical Background: The theories behind placement assessments often come from aptitude testing and are designed to measure a learner’s potential ability in a specific subject or skill area. These assessments are used to place students into appropriate instructional levels or groups, thereby optimizing the learning environment for each individual.

Example: A high school student who has just moved from another country takes an English language proficiency test. The results of this test are used to place the student in an English as a Second Language (ESL) program that best matches their current language skills.

Assessment is a multifaceted tool that serves various purposes in education. By understanding the different purposes of assessment – diagnostic, formative, summative, evaluative, and placement – educators can make informed decisions that enhance learning experiences and outcomes for their students. Through thoughtfully designed and implemented assessments, educators can unlock the full potential of each student.
