High School Teacher Job Description

A High School Teacher runs subject courses for students in grades 9 through 12: English 10, Algebra II, U.S. History, Chemistry, Spanish III, AP Biology, a personal finance semester. BLS describes the job as teaching academic lessons and the skills students will need to attend college and to enter the job market. In practice the role is built around sections. A teacher might carry several of them across two or three different courses, each with its own pacing guide, unit tests and gradebook columns.

The week starts with planning. Teachers map units to the state standards for their subject, then break those units into daily lessons with a warm-up, direct instruction, guided practice and some form of exit check. Plans live in the learning management system the district has bought, such as Canvas, Schoology or Google Classroom, and grades post to the student information system, such as PowerSchool or Infinite Campus, where families can see them. A chemistry teacher also writes lab procedures and runs safety checks on equipment; an English teacher sequences novels, essays and revision cycles; a world language teacher builds speaking assessments.

Assessment takes as much time as delivery. Teachers write and grade quizzes, unit tests, lab reports, research papers and projects, and they decide how much weight each carries. Pew Research Center describes the rise of AI in classrooms as a thorny issue for teachers. In writing-heavy courses, responses teachers use include drafting in class, collecting outlines and notes before the final paper, short oral defenses of written work, and handwritten timed responses. Some teachers also build AI use into assignments on purpose, for example asking students to critique a chatbot's answer to a historical question and correct its errors with cited evidence.

Every section holds students with different needs. Teachers carry out the accommodations written into Individualized Education Programs (IEPs) and Section 504 plans, adjust reading load for English learners, and plan extension work for students in honors or Advanced Placement sections. When a course carries college credit through a dual enrollment agreement, the teacher also follows the partner college's syllabus and grading expectations.

Outside the classroom, the job runs on communication and supervision. Teachers answer parent email, attend IEP meetings, sit in department meetings and professional learning community sessions, and take hall, lunch or bus duty. Some teachers add a stipend role: coaching a sport, advising the yearbook, sponsoring a club or running the robotics team. Teachers of juniors and seniors write recommendation letters for college applications. The rhythm follows the school calendar, with grading periods, state testing windows, AP exams and final exams marking the year.

The standard path is a bachelor's degree that combines deep coursework in the subject with a state-approved educator preparation program. Future math teachers take calculus, linear algebra and statistics alongside courses in adolescent development, classroom management and methods for teaching their subject. Science candidates add lab work, and world language candidates often need tested oral proficiency. BLS lists a bachelor's degree as the typical entry-level education and no related work experience required beyond the preparation program itself.

Student teaching is the core of that preparation. BLS notes that these programs typically include a student-teaching placement, in which prospective teachers work with a mentor teacher and get experience instructing students in a classroom. As a rough guide, the placement lasts a semester, and it is where candidates learn to pace a class period, handle a disruptive student and grade a stack of essays before the next unit begins.

Licensure comes next. BLS lists the usual state requirements as a bachelor's degree with a minimum grade point average, completion of a student-teaching program, passing a background check, and passing a general teaching certification test plus a test of knowledge in the subject the candidate will teach. Depending on the state, those exams may be the Praxis tests from ETS or a state-developed test. The license usually carries an endorsement for a subject and grade band, so a teacher licensed only in biology may need an added endorsement before taking on a physics section. Adding endorsements, usually through another content exam or extra coursework, gives a teacher more scheduling options inside a building.

Keeping the license is ongoing work. BLS notes that teachers often must complete professional development classes to keep their license or certification. Districts run their own training days, and teachers can also log hours through summer institutes, university courses and subject association conferences such as those run by the National Council of Teachers of Mathematics or the National Science Teaching Association.

For experienced teachers, National Board Certification from the National Board for Professional Teaching Standards is an advanced credential, with certificates organized by subject and student age range.

Beyond credentials, the job asks for a few practical strengths: command of the subject well beyond the textbook, the ability to explain one idea three different ways, steady classroom routines, and the patience to answer the same parent email question with care, again. Prior work in tutoring, coaching, camp counseling or a lab helps a first application.

BLS counts 1,087,500 high school teacher jobs in 2025 and projects employment to show little or no change from 2025 to 2035, a net change of -2,500 positions. The openings still come: BLS expects about 63,500 openings for high school teachers each year on average over the decade, most of them created by the need to replace teachers who transfer to other occupations or leave the labor force. For job seekers, that means the market is driven by retirements and departures in specific districts and subjects, not by new positions.

Public schools dominate hiring. BLS reports that local elementary and secondary schools employ 81% of high school teachers and private elementary and secondary schools employ 17%. In public districts, BLS notes, most states have tenure laws, which provide job security after a certain number of years of satisfactory classroom teaching. The same handbook notes that some states are developing teacher mentoring programs and teacher development courses to help with the challenges of the job.

Filling classrooms with fully certified teachers has been hard for schools. In NCES School Pulse Panel data collected in August 2024, public schools reported an average of six teaching vacancies heading into the 2024-25 school year and had filled 79 percent of them before classes resumed. The top challenges schools named were a lack of qualified candidates (64 percent) and too few candidates (62 percent). For high schools specifically, English as a second language or bilingual education stood out: 69 percent of high schools had difficulty filling a vacancy in that area with a fully certified teacher. A teacher who adds an ESL or bilingual endorsement to a content license is answering a gap that schools themselves reported.

Course requirements are shifting too. The Council for Economic Education's 2026 Survey of the States found that 39 states now require personal finance courses and 22 mandate economics for graduation. Each of those mandates has to be staffed by someone in the building, and that matters for social studies, business and family and consumer sciences teachers weighing which endorsements to hold.

Moves beyond a single classroom take several forms. Within a school, teachers step into department chair, instructional coach, dean of students or testing coordinator roles. With an administrator credential, the next steps are assistant principal and principal. Others move into district curriculum offices, write for textbook and assessment publishers, or teach methods courses in university preparation programs. Teachers who prefer to stay with students can add AP or dual enrollment courses, take on a coaching stipend, or pursue National Board Certification.

Instruction, classroom management, adolescent relationships and judgment about student thinking sit at the center of the job, and those are tasks a teacher does in the room. What has changed is the toolkit around them: AI drafting tools for lesson materials, adaptive practice platforms, and a constant need to design assignments that show what a student actually understands. The practical skill is managing both sides: using the tools for preparation while protecting the integrity of student work.

Dear Ms. Alvarado,

I am applying for the Chemistry and Physical Science teaching position at Riverside High School. I hold a Pennsylvania Instructional I certificate in chemistry for grades 7 through 12, and I completed my student teaching this spring in three sections of Honors Chemistry and two of Physical Science at Lakeview High School.

At Lakeview, my mentor teacher handed me full responsibility for a stoichiometry unit in my sixth week. I rebuilt the unit around a single question, how much baking soda it takes to neutralize a spill of vinegar, and students ran a version of that reaction in every lab period before we formalized the math. On the unit test, students who had struggled on the previous quiz closed much of the gap, and two of them asked to present their lab data at the department open house.

I take the integrity of student work seriously. When take-home lab reports began to look generated rather than written, I moved the analysis section into class, collected handwritten data tables, and added a short conversation with each lab group before grades were final. Students still use digital tools to graph and check calculations, and they now have to explain every number in their own words.

Outside the lab, I coached JV girls' soccer at Lakeview and helped run the Science Olympiad team, including two weekend invitationals. I would be glad to support Riverside's science club or an athletic program in a similar way.

I would welcome the chance to teach a demonstration lesson for your department. Thank you for considering my application.

Sincerely, Jordan Whitfield
