Priority Ranking Tool
Rank 9 items by importance using a diamond layout
Priority Ranking Tool
Enter 9 items, drag them into a diamond shape to rank by priority, and share the result with your group.
What is a priority ranking tool?
A priority ranking tool lets you arrange a set of items from most to least important using a visual layout. The most common format is the diamond 9 (also called diamond ranking), where you place nine factors into a diamond shape: one item at the top as your highest priority, two in the second row, three in the middle, two below that, and one at the bottom as your lowest priority. Teachers use it to spark critical thinking and debate. Teams use it to align on what matters most before making decisions.
How to Use the Priority Ranking Tool
This priority ranking tool takes less than a minute to set up. Here's the process.
Enter your 9 items. Type or paste the factors, options, or statements you want to rank. These could be anything: causes of a historical event, qualities of a good leader, project features to build next, or values your team cares about. You need exactly nine items for the diamond layout to work.
Drag items into the diamond. The tool shows a diamond 9 template with slots arranged in a 1-2-3-2-1 pattern. Drag each item to the slot that matches how important you think it is. The top slot is your highest priority. The bottom slot is the least important. Items on the same row share equal weight.
Discuss and debate. The real value of a ranking activity isn't the final arrangement. It's the conversation that happens along the way. Why did you put "communication skills" above "technical knowledge"? Share your screen, compare rankings with your group, and see where you agree and disagree.
Save or share your ranking. Copy the final layout or screenshot it. If you're running this as a classroom activity on Flat.social, each student group can do their own ranking in separate breakout areas, then come back together to compare results.
The tool is completely free and works in your browser. No account needed, no software to install.
Why Use a Diamond 9 Ranking Activity?
Build critical thinking skills. Ranking forces you to make tough choices. You can't put everything at the top. Students and team members have to evaluate, compare, and justify their decisions, which is a much deeper cognitive exercise than a simple list or vote.
Start better debates. Picture this: a geography class where students rank nine causes of climate change by impact. One student puts "deforestation" at the top while another ranks "industrial emissions" higher. That disagreement becomes the whole lesson. The diamond layout makes differences of opinion visible and gives everyone a concrete starting point for discussion.
Align teams before big decisions. Product teams can use this as a priority matrix generator before sprint planning. List nine potential features, have each team member rank them independently, then overlay the results. You'll quickly see where the group agrees and where you need more conversation.
Works for any subject or context. English classes rank themes in a novel. History classes rank causes of a war. Hiring committees rank candidate qualities. Scrum teams rank backlog items. The format is simple enough that anyone can pick it up in seconds, but flexible enough to apply to almost any ranking decision.
Encourage participation from quiet voices. In a typical group discussion, two or three people do most of the talking. A ranking activity gives everyone an equal say. Each person creates their own diamond first, so by the time the group discussion starts, even quieter team members already have a position to defend.
