Diploma in Biology Programs in the USA: Top 19

Every entry on this page is a two-year associate degree in biology at an American community college, and almost all of them exist for one purpose: to be the first half of a bachelor's degree taken somewhere else. Used properly that is one of the cheapest routes into a science degree in the country. Used carelessly it costs two years.

How this list is ordered: Ordered by each university's QS World University Rankings position where it has one, then by research citations recorded by OpenAlex; one programme per university, and universities with neither measure are left out.

10 Diploma Biology

Coastline Community College

  • DeliveryOn campus
  • Study modeFull time
  • Duration2 years
  • StartsFall, Spring
  • Research citations1,725

Coastline is known for distance and flexible teaching, which creates one specific problem in biology.

The taught content covers cellular biology, genetics, ecology and physiology well enough. The laboratory component is the constraint, since it cannot be completed at a distance, so how and where those sessions run matters more here than anywhere else on this subject.

Warren County Community College

  • DeliveryOn campus
  • Study modeFull time
  • Duration2 years
  • StartsFall, Spring
  • Research citations587

Biology at Warren County Community College, a small institution in New Jersey, running two years.

18 Diploma Biology

Little Priest Tribal College

  • DeliveryOn campus
  • Study modeFull time
  • Duration2 years
  • StartsFall, Spring

19 Diploma Biology Transfer Pathway

South Central College

  • DeliveryOn campus
  • Study modeFull time
  • Duration2 years
  • StartsFall, Spring
  • Research citations67

South Central College names the purpose in the title: this is a transfer pathway, matched to what receiving universities expect.

A named pathway is the most reliable transfer credential available at this level, because the course list has already been aligned rather than assessed afterwards. The biology foundation itself is broad, covering the main areas before the move to a four-year institution.

Associate degrees in biology: common questions

Will a university accept these credits?

It depends on the agreement between the two institutions, not on the credential itself. Confirm with the receiving university that an agreement covers biology, that the credit counts towards the major rather than only general education, and specifically that the laboratory sciences transfer — those are the courses most often refused.

Can I get a laboratory job with an associate degree in biology?

Generally not with this credential. Biology technician roles usually want a bachelor's degree, and the clinical laboratory professions have their own accredited programmes and certification examinations. If immediate employment is the aim, look for a named technical programme such as clinical laboratory technician or biotechnology technician instead.

Is this a good route for pre-medical study?

It works, and it is far cheaper. Two cautions: check that the specific prerequisite courses each professional school requires are satisfied by the community college versions, and be aware that some admissions committees prefer prerequisites completed at a four-year institution. The common solution is to transfer and complete upper-level science there.

What should I ask about credits?

The total credit count, which is recorded for only one entry here — 90 credits over six quarters. Ask every college for that figure, then ask the receiving university how many of those it would accept and how many towards the biology major specifically. Get the answer in writing.

Can I study biology online at this level?

Not completely. Every entry here is recorded as on campus and full time, and the laboratory component is both essential and the part universities scrutinise on transfer. Many colleges teach lectures online with on-campus laboratories — ask whether that hybrid version transfers identically before enrolling in it.
