K–12 means kindergarten through twelfth grade. Undergraduate study usually works toward an associate or bachelor's degree. Graduate study usually follows a bachelor's and may lead to an advanced degree.
These labels describe broad parts of US education rather than every school type.
"The company sells software to K–12 schools and universities."
The customers include schools through high school, plus colleges and universities.
What does K–12 mean?
The K stands for kindergarten, while 12 means twelfth grade. That is usually the final high-school grade. You may see the term in the following forms.
- K–12
- K-12
- K12
All three forms usually mean the same thing. K–12 is common in edited text, while K12 often appears in company names and product labels.
The standard spelling is kindergarten, not kindergarden. A simple pronunciation is KIN-der-GAR-tən. Say K–12 as kay through twelve.
K–12 is a broad category covering elementary and secondary education. One school may serve only part of that range. A K–12 school can mean one school serving the full span.
Does K–12 include pre-K?
Not literally, because pre-K, or prekindergarten, comes before kindergarten. Groups covering early childhood may write pre-K–12 or PK–12. They may also say early childhood and K–12.
In casual use, someone may discuss K–12 while also mentioning pre-K. A policy or benefit should state its exact coverage.
"Does the dependent-education benefit cover pre-K, or only K–12 tuition?"
This question matters because the two categories have different boundaries.
What does undergraduate mean?
In the United States, an undergraduate student seeks an associate or bachelor's degree. EducationUSA says two-year colleges commonly offer associate degrees. Colleges, universities, and specialized institutes offer bachelor's degrees.
Common forms include:
- undergrad: informal noun or adjective
- undergraduate student: standard formal phrase
- undergraduate degree: an associate or bachelor's degree
- undergraduate program: a program leading to one of those degrees

Graduate study usually follows a bachelor's degree and offers more specialized work. Common advanced degrees include master's and doctoral degrees. Grad school is a common informal form.
"She is taking one course per semester in grad school."
Law, medicine, and other fields may use the term professional school. Institutions may classify these programs differently for aid or benefits. Use the institution's official label on forms.

What can you say naturally?
For a résumé or interview:
"I have five years of product experience in the K–12 education market."
For benefits:
"Does the reimbursement policy cover graduate certificates, or only degree programs?"
For parental scheduling:
"The K–12 schools are closed for a district holiday, so I will work from home."
For your education:
"My undergraduate degree is in finance, and I later completed a graduate program in analytics."
Recognition versus production
Recognize K–12 as an industry or policy category. It rarely names one child's exact level in conversation. A parent will more likely name elementary, middle, or high school.
Use undergraduate and graduate when degree level matters. In casual speech, college and grad school may sound more natural.
If someone's education does not fit these labels, ask about the credential. Do not force an exact match:
"What type of program was it?"
Avoid assumptions about status
These categories describe education levels, not intelligence or professional value. Some roles require a graduate degree; many do not. K–12 work also includes many roles beyond teaching.
For hiring, pay, or promotion, tie education requirements to the work. Follow the relevant policies. In small talk, avoid asking why someone skipped a degree. Cost, access, health, immigration, care work, and personal goals can shape that choice.
