In Setup -> Progress Report Templates, a user can view all of the available templates that have been created, edit them, and also create new templates. See here for How To - Create, Copy and Edit a Progress Report Template.
A Progress Report Template is a group of Progress Report settings that are determined by administration. The settings include a Mastery Scheme and various attributes of the particular report (i.e. detail level, inclusion of mastery bars, score conversions, etc).
A default Progress Report Template is selected in Mastery Options to be the main report organization when a set of reports is generated by a user (including by teachers).
In the list of templates, clicking on the name of a template opens the details of the template with options to edit its elements.
For each school in a district, either a copy __ of an existing template can be made or a new template can be created.
