Basically, I need a way for the code to check, "Does standard1 appear in chapter 1?" If yes, put a checkmark. If not, leave blank.
Something like this? (I've kept it simple but more verbose: you could extend \learned instead to make it neater.)

\setevalue{standard1}{Students will learn how to navigate the library catalog efficiently.}
\setevalue{standard2}{Students will learn how to use a library card to access various services.}
\setevalue{standard3}{Students will learn to locate and select appropriate resources across different media.}
\setevalue{standard4}{Students will learn to utilize digital databases for academic research.}
\setevalue{standard5}{Students will learn to operate self-checkout stations for streamlined borrowing.}
\setevalue{standard6}{Students will learn to manage due dates and renew borrowed materials responsibly.}
\setevalue{standard7}{Students will learn the fundamentals of the library classification system.}
\setevalue{standard8}{Students will learn to evaluate information sources for credibility and relevance.}
\setevalue{standard9}{Students will learn to use reference materials to support academic inquiries.}
\setevalue{standard10}{Students will learn to adhere to library policies and ethical usage guidelines.}
\setevalue{standard11}{Students will learn to reserve study areas and meeting spaces effectively.}
\setevalue{standard12}{Students will learn to access and navigate digital library resources.}
\setevalue{standard13}{Students will learn to engage with library programs and community events.}
\setevalue{standard14}{Students will learn to utilize interlibrary loan services for extended research.}
\setevalue{standard15}{Students will learn to apply proper citation methods for materials sourced from the library.}
