Louisiana law sets no specific minimum age to be a teacher, but the practical floor is set by the credentials you need: a bachelor’s degree from a regionally accredited college or university, completion of a state-approved teacher preparation program, and passing scores on the Praxis exams. Because those requirements take four years of college at a minimum, most new Louisiana teachers are 21 or 22 when they first stand in front of a class. A few finish earlier, and some routes let you work in a classroom before you’ve met every requirement, but the degree is the real gatekeeper.
What the Law Actually Requires
The certification standards live in Louisiana Revised Statutes Title 17 and in Bulletin 746, the administrative code issued by the Board of Elementary and Secondary Education (BESE). Neither sets an age minimum. What they require is academic preparation.
Every candidate for a standard Louisiana teaching certificate needs a bachelor’s degree from a regionally accredited institution. The state recognizes an undergraduate teacher preparation program for those pursuing an education degree, and a post-baccalaureate pathway for those who already hold a bachelor’s in another field. Both include coursework aligned with state standards and a yearlong teaching residency.1Louisiana Department of Education. Pathways to Teaching
GPA matters. Under Bulletin 746, applicants for a Level 1 professional certificate must have at least a 2.20 cumulative undergraduate GPA and a 2.50 GPA in the teacher preparation program.2NOLA Public Schools. Bulletin 746 – Louisiana Standards for State Certification of School Personnel You also need passing scores on the Praxis Core Academic Skills for Educators (reading, writing, and mathematics) and on the Praxis Subject Assessment in the content area you plan to teach.3Praxis (ETS).

The Youngest You Could Realistically Start
Working backward from the degree requirement: a student who begins college at 18 and finishes a four-year undergraduate teacher preparation program on schedule can be certified at 22. Students who enter college with dual-enrollment or AP credit, or who carry heavy course loads, sometimes finish the bachelor’s and the preparation program in three years and start teaching at 21. Younger than that is unusual because the yearlong teaching residency and the full degree have to be completed before you receive a Level 1 professional certificate.
The Level 1 certificate itself is valid for three years initially, with up to two one-year extensions available at the request of a Louisiana employer.4Louisiana Department of Education.

Working in a Classroom Before Full Certification
You don’t have to wait for a full Level 1 certificate to be in a Louisiana classroom. Several options start earlier, each with its own prerequisites.
Substitute Teaching
Substitute teaching is the earliest way in. Louisiana handles substitutes at the district level rather than through a state-issued permit — the Department of Education does not issue substitute credentials, and each district sets its own hiring criteria. The minimum education requirement is a high school diploma. Substitutes who don’t hold at least an associate’s or bachelor’s degree may need to demonstrate tenth-grade proficiency in reading and mathematics through standardized testing. The same fingerprint-based criminal background check that applies to full-time teachers applies to substitutes.5Louisiana State Legislature. Louisiana Code RS 17:15 – Criminal History Review
In practice, that means a recent high school graduate who meets a given district’s requirements could substitute at 18. Whether that happens depends entirely on local policy — age minimums, if any, come from the district, not the state.
Practitioner Teacher Program
The Practitioner Teacher Alternate Certification Program lets you teach full-time while completing your certification coursework, which is useful for people who already have a bachelor’s degree in another subject. Admission requires a bachelor’s from a regionally accredited institution, a 2.50 undergraduate GPA, and passing Praxis scores (candidates admitted after December 2019 with a lower GPA may qualify by completing an interview with the program’s admissions officer).6Teach Louisiana. Practitioner Teacher Alternate Certification Program
Once enrolled, you receive a Practitioner License 1 (PL1), valid for one school year and renewable annually for up to three years while you complete the program. You must finish at least six semester hours of coursework per year to keep the license active. Total program hours range from 24 to 33 credit hours depending on the grade band, which covers PK–3, 1–5, 4–8, 6–12, all-level K–12 subjects like art and music, and special education (mild to moderate).6Teach Louisiana. Practitioner Teacher Alternate Certification Program
Some candidates can skip the Praxis Core: holders of a graduate degree, an ACT composite of 22, or an equivalent SAT score are exempt.6Teach Louisiana. Practitioner Teacher Alternate Certification Program
Provisional Teaching Permit
BESE can also issue a provisional teaching permit to someone who hasn’t passed all required exams but holds at least a bachelor’s degree in the subject area with a 2.50 GPA and has passed the content knowledge exam.7Louisiana State Legislature. Louisiana Code RS 17:8.3 – Provisional Teaching Permit
Background Check: Required at Any Age
Age is not a disqualifier, but a criminal record can be. Every prospective teacher in Louisiana must clear a fingerprint-based criminal background check before being hired. School boards submit the applicant’s fingerprints to the Louisiana Bureau of Criminal Identification and Information, which screens against state and federal records. This requirement applies to all school employees, including teachers, substitutes, bus operators, and janitors.5Louisiana State Legislature. Louisiana Code RS 17:15 – Criminal History Review
Louisiana maintains a detailed list of disqualifying offenses under RS 15:587.1(C), including crimes of violence as defined in RS 14:2(B), sex offenses as defined in RS 15:541, drug manufacturing and distribution charges under Title 40, and specific offenses against children and families. A conviction or nolo contendere plea to any listed offense bars you from employment, even if adjudication was withheld or a pardon or expungement was granted.8Justia Law. Louisiana Revised Statutes 15:587.1 – Provision of Information Anyone whose name appears on the Department of Children and Family Services’ state central registry on or after August 1, 2018, is also ineligible for hire, and the scope extends to equivalent convictions from other states.5Louisiana State Legislature. Louisiana Code RS 17:15 – Criminal History Review
If You’re Coming In Older or From Another State
If you already hold a bachelor’s degree in a non-education field and want to switch careers, the post-baccalaureate pathway is the university-based route to certification. It uses a competency-based curriculum and, like the undergraduate program, includes a yearlong teaching residency.1Louisiana Department of Education. Pathways to Teaching
If you’re a certified teacher moving in from another state, Louisiana doesn’t have blanket reciprocity but will issue one of two credentials. A Level 1 Professional Certificate goes to applicants who’ve already met Louisiana’s Praxis requirements. An Out-of-State (OS) Certificate, valid for three years and non-renewable, goes to those who haven’t; during that window, you satisfy the exams or qualify for an exemption.9Teach Louisiana. Out-of-State Certification Application Packet
The exemption worth knowing: if you have at least three years of successful teaching experience in another state and then teach on an OS certificate for one year in a Louisiana school, you can receive a Level 1 certificate without taking the Praxis, provided your superintendent recommends you for continued employment. If you haven’t taught within the past five years, you’ll need six semester credits in your teaching field from a regionally accredited institution before applying.9Teach Louisiana. Out-of-State Certification Application Packet
So the short version: there is no legal minimum age to teach in Louisiana. The degree, the preparation program, and the Praxis are what set the earliest realistic start date. For most new teachers, that’s the year they turn 22.
