Overriding the FLUID templates 

This is how the templates are assigned in the higher_education_package:

plugin.tx_highereducationpackage.contentelements {
	templateRootPaths {
		5 = EXT:higher_education_package/Resources/Private/Templates/ContentElements/
		10 = {$plugin.tx_highereducationpackage.contentelements.view.templateRootPath}
	}
	partialRootPaths {
		5 = EXT:higher_education_package/Resources/Private/Partials/ContentElements/
		10 = {$plugin.tx_highereducationpackage.contentelements.view.partialRootPath}
	}
	layoutRootPaths {
		5 = EXT:higher_education_package/Resources/Private/Layouts/ContentElements/
		10 = {$plugin.tx_highereducationpackage.contentelements.view.layoutRootPath}
	}
}
Copied!

If you want to overwrite the templates you can set the corresponding path-constant or set new paths with a increased number.

plugin.tx_highereducationpackage.contentelements {
	templateRootPaths.20 = EXT:your_extension_key/Resources/Private/Templates/ContentElements/
	partialRootPaths.20 = EXT:your_extension_key/Resources/Private/Partials/ContentElements/
	layoutRootPaths.20 = EXT:your_extension_key/Resources/Private/Layouts/ContentElements/
}
