However, I did attend a GT program during elementary school. This school was a "regular" public elementary school in the sense it had a local geographic boundary, and kids in the area attended this as their default public school. However, then kids who qualified for GT would be bussed in from around the county to go to this school.
Within the school, past the 3rd grade classes were segmented into GT and "base" classes (i.e. non-GT). The "base" classes were local kids who did not qualify for the GT program. GT qualification was based off a single test score, taken in the second grade. Kids in the GT and base classes were often respectively referred to as GT or base kids.
In retrospect, it's always appeared super detrimental to me that those kids were called "base" as if they were a somehow more basic version of the GT kids. The name "base" in itself was probably intended as a kind euphemism, to not otherwise default to calling them non-GT kids, i.e. non Gifted nor Talented.
Anyway, all of this to say GT programs probably have a place, but in my own anecdotal experience they were not always executed flawlessly.
Some parts of this are probably good advise, at least with respect to clocking titular promotions. No disagreement around visibility of delivered "big wins" being key.
However, I feel like this article is subliminally pro-management, with the thesis statement essentially being just make your manager (and their manager) happy. But what happens when there's no clear direction from management on what the team's goals are? Or when priorities shift on a weekly, or even daily basis? It seems pretty hard to deliver anything meaningful, if by the time you're finished they've already moved on to the next shiny thing.
Additionally, in my experience this "make your manager happy" approach goes hand-in-hand with a "yes boss" manager-subordinate relationship. Managers are empowered to flurry out executive dispatches on what, when, and how things ought to be done, and engineers are encouraged to follow orders. Results are normally not great.
