What is the best description of a collection of work samples submitted for a teaching position?

A collection of work samples submitted for a teaching position is best described as a portfolio. A portfolio showcases a teacher’s experiences, skills, and accomplishments, providing tangible evidence of their teaching effectiveness. It typically includes a variety of work samples, such as lesson plans, student assessments, classroom management strategies, and examples of student work, all aimed at demonstrating the candidate's qualifications and instructional competencies.

Portfolios also allow teachers to reflect on their practices and growth over time, providing a comprehensive view of their professional journey. This contrasts with a résumé, which is a brief summary of professional experiences and skills; a license, which affirms a teacher’s qualifications to teach; and a credentials file, which typically comprises various documents like transcripts and letters of recommendation, but does not present the dynamic body of work that a portfolio does.
