Nominal Group Technique (NGT) in Educational Institutions

Using the Delphi Method for Effective Decision-Making in Educational Leadership

What is Nominal Group Technique -NGT?

Nominal Group Technique (NGT) is a structured method for group brainstorming that encourages contributions from everyone. It involves a multi-step process designed to generate ideas and prioritize them. The primary goal of NGT is to ensure that all participants have an equal opportunity to contribute, which is particularly useful in diverse groups.

The NGT process begins with a clear statement of the problem or question. Participants first write down their ideas silently and independently. This step ensures that each person’s ideas are captured without the influence of others’ opinions. Once everyone has listed their ideas, participants take turns sharing them with the group, typically in a round-robin format. This method prevents domination by a few individuals and promotes balanced participation.

After all the ideas are presented, the group discusses each one for clarity and understanding. This discussion is critical as it allows participants to elaborate on their ideas and ask questions about others’ contributions. It helps ensure that everyone has a clear understanding of each idea before moving on to the next step. The facilitator plays a key role in guiding this discussion and keeping it focused and respectful.

The final step involves ranking the ideas. Each participant ranks the ideas individually, usually by assigning points or placing them in order of preference. The facilitator then aggregates these rankings to identify the most favored ideas. This ranking process helps the group reach a consensus on the most important or promising solutions. NGT thus combines the benefits of individual idea generation with group discussion and prioritization, making it a powerful tool for decision-making in various settings.

Understand Nominal Group Technique in Point-wise

The Nominal Group Technique is a structured method for group brainstorming that encourages contributions from everyone and helps prioritize ideas.


Silent Generation of Ideas: Each team member writes down his ideas independently.

Round-Robin Sharing: Members take turns sharing one idea at a time without discussion, until all ideas are listed.

Clarification: The group discusses each idea to ensure everyone understands them, but without debating their merits.

Voting and Ranking: Members vote on the ideas, usually by ranking them. The votes are tallied to identify the most favored solutions.


Equal Participation: Ensures that all team members have an equal opportunity to contribute.

Efficient Prioritization: Helps the team quickly identify the most popular or feasible ideas.


Application Example: Enhancing School Safety

Suppose you are using NGT to enhance school safety measures:

Idea Generation: Each team member (teachers, staff, students, and parents) writes down their suggestions for improving school safety.

Sharing Ideas: In a round-robin fashion, members share their ideas, which are recorded on a board.

Clarification: The group discusses each idea briefly to clarify them, ensuring everyone understands the proposals.

Voting: Members rank the ideas based on their perceived importance and feasibility.

Result: The ideas with the highest rankings are prioritized for implementation.

“Improving Collaborative Decisions in Schools- The Power of Nominal Group Technique (NGT)”

Collaborative decision-making is essential for effective school leadership. Understanding how team dynamics influence decision-making and mastering consensus-building techniques can lead to more informed and widely supported decisions.

The composition and dynamics of a team significantly influence the quality and efficacy of its decision-making processes. Diverse teams, encompassing a wide range of perspectives and skills, are generally more effective in identifying innovative solutions and making well-rounded decisions. We also observed it that such diversity can also lead to conflicts and communication barriers, necessitating the implementation of structured techniques to ensure cohesive and productive collaboration. Effective team dynamics, characterized by mutual respect, clear communication, and a shared goal, are crucial for exploring the full potential of diverse teams and facilitating effective decision-making.

To address the challenges posed by diverse team compositions, structured decision-making techniques like the Delphi Method and the Nominal Group Technique (NGT) can be invaluable. The Delphi Method promotes iterative rounds of anonymous feedback from experts to converge on a well-considered decision, minimizing the influence of dominant personalities and group think. The NGT encourages equal participation through independent idea generation and structured discussions, leading to a collective agreement that respects individual contributions.
