Four Years of Teaching Working Professionals: What Changed

Published 18 May 2026 by Yasmin Halloran

Beesy Academy has been running since 2022. We have taught a lot of cohorts since then, and a fair amount of what we believed at the start turned out to be wrong. Here is an honest account of what moved.

We stopped using clean sample data

When I built the first version of Spreadsheet Analysis for Decision Makers I used tidy example files. Every date parsed, every category was spelled the same way, and students got through the exercises smoothly and felt capable. Then they went back to work, opened a real export, and got stuck in the first ten minutes.

Clean data teaches the wrong instincts. It teaches you that the analysis starts when you open the file. So we replaced everything with genuinely untidy material: duplicate rows, three date formats in one column, a category field somebody typed by hand. The sessions got slower and the complaints went up in week two. The results after the course went up a great deal more.

We stopped adding content to fill the weeks

Our early courses were longer than they needed to be, because a longer syllabus looked like better value. What actually happens is that padding pushes the practice out. The week where somebody was supposed to apply the tool to their own work turned into a week where they learned a second tool they will never use.

Now every course is the length the material genuinely needs. Focus and Workload Design is five weeks and will not be extended. The longest course we run is Front End Development Essentials at ten weeks, and it is that long because building a real site takes that long.

We got stricter about prerequisites

We used to let anybody into any course, on the principle that adults can judge their own readiness. Mostly they can, but the exceptions were painful. Someone arriving at an advanced course without the ground under them does not just struggle themselves, they slow the room down, and the honest thing is to say so before they pay.

So now we ask about your situation when you apply, and a few times each quarter we tell somebody to take a different course first, or to come back next quarter. Almost nobody is annoyed by this. Several have come back later and said it was the right call.

What has not changed

Cohorts are still capped at sixteen, for exactly the reasons Ilene set out in 2022. Every instructor still practices what they teach; nobody here teaches full time. And every course still ends with something you made, applied to your own work, that you can show to somebody.

That last one is the whole point. Four years in, the thing students mention when they write to us is almost never a concept from a session. It is the report they defended, the conversation they finally had, or the site they published. The teaching exists to produce those.
