In 2019 I became a certified RStudio instructor for tidyverse. I wrote about that experience in this post.
To get certified you have to take a teacher exam and a technical exam on tidyverse and/or shiny.
In this post by Greg Wilson in the RStudio Education blog is the test I took for teaching and tidyverse in English.
In this same post but choosing Spanish as a language you can find the sample exam in Spanish.
