IPEDS publishes completions data for various award and degree levels. Some are intuitive; others require some explanation. Below are the definitions taken from IPEDS' glossary of terms for the Completions component of their data.
Associate Degree
An award that normally requires at least 2 but less than 4 years of full-time equivalent college work.
Bachelor's Degree
An award (baccalaureate or equivalent degree, as determined by the Secretary, U.S. Department of Education) that normally requires at least 4 but not more than 5 years of full-time equivalent college-level work. This includes all bachelor's degrees conferred in a 5-year cooperative (work-study) program. A cooperative plan provides for alternate class attendance and employment in business, industry, or government; thus, it allows students to combine actual work experience with their college studies. Also includes bachelor's degrees in which the normal 4 years of work are completed in 3 years.
Certificate
A formal award certifying the satisfactory completion of a postsecondary education program.
Doctor's Degree--Other
A doctor's degree that does not meet the definition of a doctor's degree - research/scholarship or a doctor's degree - professional practice.
Doctor's Degree--Professional Practice
A doctor's degree that is conferred upon completion of a program providing the knowledge and skills for the recognition, credential, or license required for professional practice. The degree is awarded after a period of study such that the total time to the degree, including both pre-professional and professional preparation, equals at least six full-time equivalent academic years. Some of these degrees were formerly classified as first-professional and may include: Chiropractic (D.C. or D.C.M.); Dentistry (D.D.S. or D.M.D.); Law (J.D.); Medicine (M.D.); Optometry (O.D.); Osteopathic Medicine (D.O); Pharmacy (Pharm.D.); Podiatry (D.P.M., Pod.D., D.P.); or, Veterinary Medicine (D.V.M.), and others, as designated by the awarding institution.
Doctor's Degree--Research/Scholarship
A Ph.D. or other doctor's degree that requires advanced work beyond the master's level, including the preparation and defense of a dissertation based on original research, or the planning and execution of an original project demonstrating substantial artistic or scholarly achievement. Some examples of this type of degree may include Ed.D., D.M.A., D.B.A., D.Sc., D.A., or D.M, and others, as designated by the awarding institution.
Master's Degree
An award that requires the successful completion of a program of study of at least the full-time equivalent of 1 but not more than 2 academic years of work beyond the bachelor's degree. Some of these degrees, such as those in Theology (M.Div., M.H.L./Rav) that were formerly classified as "first-professional", may require more than two full-time equivalent academic years of work.

An award that requires completion of an organized program beyond the master's degree, but does not meet the requirements of academic degrees at the doctor's level.

It is designed for persons who have completed a baccalaureate degree, but does not meet the requirements of a master's degree.NOTE: Even though Teacher Preparation certificate programs may require a bachelor's degree for admission, they are considered sub-bacalaureate undergraduate programs, and students in these programs are undergraduate students.
