Consider reviewing the material of the QGIS Academy, which was funded by a US Department of Labor grant and is available via a Creative Commons BY 4.0 license, with the module and lab content downloadable from their github account.

If you use the content, consider contributing back to the project. I understand they need some MSWord -> Markdown conversion help.

Specifically, it is based upon the Geospatial Technology Competency Model framework.

Each section, like GST 101 Introduction to Geospatial Technology Using QGIS, has numerous instructor-led videos freely available. Whereas, the currently running actual for-credit courses can be registered for via Del Mar College, located in Texas.
