Yes, it's generally acceptable to selectively include or exclude qualifications on your resume based on the specific job requirements.

The goal of a resume is to highlight the skills and experiences most relevant to the job you're applying for. In your case, if the job posting only requires a degree, including your master's degree might not add significant value and could potentially overqualify you.

If you omit, it can help you appear more competitive for the role, as it might be perceived that you're not overqualified. But you might miss out on opportunities that specifically seek master's-level candidates.

However, it's important to be honest and transparent. If you're asked about your qualifications during an interview, be prepared to explain why you chose to omit certain information.

A better approach might be to tailor your resume for each specific job application. Highlight the skills and experiences that are most relevant to the job, and adjust the level of detail in your qualifications section accordingly.

Ultimately, the decision of whether to include or omit a qualification depends on the specific job and your individual circumstances.
