Executive Summary

David Fortin (Copilot educator, M365 specialist) presents a five-level progression for Microsoft 365 Copilot mastery: Explorer, Prompter, Copilot Beginner, Agent builder, and Co-Work automation.

Five Levels

Explorer → Prompter → Copilot Beginner → Agents → Co-Work, a skill ladder.

GCES

Goal, Context, Expectations, Source — structured prompting that transforms output.

Agents

Pre-built and custom specialist bots outperform generic prompts.

Co-Work

Multi-step cross-app automation, e.g. migrating testimonials into Excel.

Finding 1: The Five-Level Mastery Ladder

Fortin frames Copilot skill as a ladder rather than a binary "use it or not" state. Level one (Explorer) is pre-built prompts and web-search-style questions in apps like Outlook, which yield generic results because the user provides no context. Levels escalate through structured prompting, app integration with file and brand awareness, custom agents, and finally Co-Work, which chains multiple steps across apps autonomously. The framing positions Copilot mastery as a skill progression, not a feature tour [Source 1].

Finding 2: The GCES Prompting Framework

The Prompter level introduces Goal, Context, Expectations, and Source. In the demo, a weekly sales report PDF from a fictional pizzeria is summarized two ways: a basic "summarize this report" prompt versus a GCES-structured prompt that states targets (47k weekly, food costs under 30%), desired outputs (three things that went right, three that went wrong, what needs attention first), and the source. The structured result includes an actionable table, assigns owners, and cites specific PDF sections (section four, the oven), demonstrating that prompt structure directly controls output usefulness [Source 1].

Finding 3: Copilot Inside Productivity Apps

Level three covers Copilot in PowerPoint, Excel, and Word. Key demonstrated techniques: enable "allow editing" mode so Copilot edits the file directly, attach files or OneDrive content, select a brand so the deck matches company assets, and explicitly pick a model (Claude Opus 5 or GPT 5.6 in his environment) instead of auto. Fortin generated an eight-slide presentation from a PDF in about nine minutes, then issued a follow-up prompt that pulled the latest email from Outlook into a new slide matching the deck style, showing cross-app data access [Source 1].

Finding 4: Agents as Specialists

Level four distinguishes pre-built Microsoft agents from custom agents. The Analyst agent ran a 17-step comparison of two weekly sales reports and produced week-over-week analysis, charts, and a comparison table. Fortin argues agents outperform ordinary prompts for their specialty because they are trained and instructed for that single task. He also shows custom agents: a "PowerPoint Guru" that prepares presentation question banks, deck summaries, and top risks, and a LinkedIn post agent that generates three hook ideas and a post from a pasted transcript. Custom agents are configured with plain-language instructions in the agent builder [Source 1].

Finding 5: Co-Work for Multi-Step Automation

The capstone demonstration uses Copilot Co-Work to migrate roughly 70 course testimonials from templated Thinkific notification emails into a structured Excel spreadsheet, which Fortin then imported into the Senja testimonial platform. He provided an example image of the email format so Co-Work understood the extraction pattern, and ran the workflow since January 1, 2026. The run cost approximately 783 credits (about $7.83). Fortin estimates the equivalent manual copy-paste would have taken 3 to 4 hours, framing this as a small-cost, high-return automation pattern [Source 1].

Finding 6: Practical Gatekeepers and Prerequisites

Several features require a paid M365 Copilot license: level 3.5 follow-up slide generation, agents, and Co-Work. Fortin notes admins can turn off agents in tenant policy, and that Copilot buttons appear across 365 apps depending on the license label. Model availability also varies by tenant, with Claude and GPT offered alongside Microsoft models in his setup. These constraints matter for organizations planning Copilot rollout, since feature availability is not uniform [Source 1].
