To share results with another teacher but prevent data alteration, which option is best?

Choosing the option of a Protected Range is ideal when the goal is to share results with another teacher while simultaneously preventing any alterations to the data. A Protected Range allows you to restrict certain cells or ranges within a Google Sheet, meaning that those who access the document can view the data but cannot change it unless they have the required permissions.

This feature ensures that the integrity of your data is maintained since only the owner or individuals who have been granted specific editing rights can make changes. By sharing a document in this way, you can collaborate effectively while preventing unwanted changes, making it a suitable choice for scenarios where data accuracy is critical.

In contrast, an Editable Sheet would allow others to change or modify the data, which contradicts the need to prevent alterations. A Shared Drive facilitates access to a collection of files, but it does not inherently protect the data in individual files. A Read-Only View may seem like an option to prevent edits, but it is not a feature that can be actively set in Google Sheets in the same manner as a Protected Range, as it typically applies to entire documents rather than specific data sets within a sheet.
