Bachelor of Science vs. Bachelor’s Degree

The useful distinction is grammatical and editorial at once: the formal title uses Bachelor of Science without a possessive, while the generic phrase uses bachelor’s degree. University style guides also show why capitalization should be presented as a house-style boundary rather than an absolute rule for every document.

Quick answer

Use Bachelor of Science for the formal degree name. Use bachelor’s degree for the generic degree description; bachelor’s is possessive and takes an apostrophe. Do not write “Bachelor’s of Science.” Capitalization of degree names can follow an institution’s house style, so distinguish the grammatical form from local editorial policy.

Are you naming the formal credential rather than referring generically to the degree level?

Examples

Example

The formal degree name uses Bachelor of Science.

Example

The generic degree phrase uses the possessive bachelor’s.

Further guidance

Formal Name

Write the formal degree title as Bachelor of Science; do not insert a possessive apostrophe into the title.

Generic

Write bachelor’s degree for a general reference; the possessive form takes an apostrophe.

Style Boundary

Institutional style guides commonly capitalize formal degree names and lowercase generic references, but local house style governs capitalization in institutional publishing.

Wrong Hybrid

Avoid “Bachelor’s of Science,” which mixes the generic possessive with the formal of-construction.
