What Is CALS at the University of Idaho?

Updated

CALS stands for the College of Agricultural and Life Sciences at the University of Idaho. It is the college within U of I that covers agriculture and the life sciences — fields such as animal science, plant science, and food science — and it is the place to look if you want a degree, research experience, or a career path in those areas. This explainer is for prospective students, transfer students, and anyone trying to understand how CALS fits into U of I before applying or choosing a major.

What CALS means and where it sits at U of I

CALS is an academic college, not a separate school or a standalone program. At U of I, colleges group related degrees and departments, and CALS is the one organized around agriculture and life sciences.

The University of Idaho describes itself as Idaho's first and only Carnegie R1 research university, with more than 200 areas of study and hands-on experience that puts learning into action. That research classification matters for CALS students because agricultural and life science fields are lab- and field-intensive: the R1 designation signals that research activity is part of the institution's core, not an add-on.

What CALS covers

CALS spans the science of producing food and managing natural systems, plus the biology that underpins them. Based on the fields associated with the college, subject areas include:

  • Animal science — livestock and animal biology, nutrition, and production
  • Plant science — crop science, soils, and plant biology
  • Food science — how food is processed, preserved, and kept safe
  • Agriculture more broadly — the production and business side of farming and related industries
  • Life sciences — the biological foundations that connect these applied fields

If your interest is in how food gets from a field to a table, how animals and crops are managed, or the biology behind those systems, CALS is the relevant college. If your interest is anatomy or health professions, note that U of I frames its degree range as running "from agriculture to anatomy" — those are different paths, so check which college houses the specific major you want.

Degrees, research, and hands-on learning

CALS students can pursue both undergraduate and graduate degree programs. The practical way to see what is offered is to browse U of I's degrees and majors listing and filter for programs in the college, rather than assuming a major exists because the field sounds related.

Two features of the U of I experience are worth weighing for CALS specifically:

  1. Research access. As an R1 university, U of I supports research activity across its colleges. For CALS students, that can mean working in labs or field projects tied to agriculture and life sciences.
  2. Statewide footprint. U of I describes a statewide footprint that "opens doors to discovery and opportunity." Agriculture is a statewide industry in Idaho, so college programming and research connections are not confined to the Moscow campus alone.

The main campus is in Moscow, described as an ivy-covered campus with a supportive community. Campus visits are one of the listed ways to learn more, which is useful if you want to see facilities tied to a specific CALS program before committing.

Admissions, scholarships, and next steps

U of I lists admission requirements separately for first-year, transfer, international, and graduate students, so the requirements you follow depend on which category you fall into. Check the admission requirements page for your student type before applying.

On cost, U of I states that it keeps education affordable with low tuition, generous scholarships, WUE opportunities, and financial aid, available for recent grads, transfer students, and out-of-state learners. WUE refers to the Western Undergraduate Exchange, a tuition arrangement for students from participating western states — worth checking if you are an out-of-state applicant from that region. Note that the source material does not list specific tuition figures or scholarship amounts, so confirm current numbers directly with the university rather than relying on general statements.

A practical sequence if you are considering CALS:

  • Identify the specific major you want, then confirm it sits in CALS
  • Match yourself to the correct admission requirements category (first-year, transfer, international, or graduate)
  • Check scholarship, WUE, and financial aid options for your situation
  • Request more information from U of I or schedule a campus visit to see the relevant facilities

How CALS relates to U of I overall

U of I has earned several rankings that apply to the university as a whole, including being named the No. 1 Best Value Public University in the Nation by U.S. News & World Report — a spot it says it has held for seven consecutive years among the country's best — plus recognition as Best Online College in Idaho (Forbes), Most Beautiful College in Idaho (MSN), Best Professors in Idaho (Niche), and a Green School for Sustainability (Princeton Review).

These are institution-wide rankings, not CALS-specific ones, so treat them as context about U of I rather than as evidence about any single program. For a decision about CALS, the more useful signals are the specific degree offerings, research opportunities, and the fit between your interests and the college's fields.
