Computer Science Teacher Job Description

A Computer Science Teacher runs the computing courses in a middle or high school: introductory programming, AP Computer Science Principles, AP Computer Science A, and electives that may include cybersecurity, data science, game development or robotics. On paper the schedule looks like any secondary teaching job: several sections, a planning period, duty assignments and parent email. The difference is what happens inside the room. Students spend much of each class period writing, running and fixing code, and the teacher spends it moving between screens, reading error messages over shoulders and deciding which bug is worth a whole-class pause.

Planning starts with sequencing. A first-year course has to take students who have never written a loop to the point where they can decompose a problem, write functions and test them, while a few students in the same section already build their own projects at home. Teachers handle that spread with tiered tasks, extension challenges and pair programming, where two students share one problem and trade the keyboard. Assessment leans on artifacts: programs, short written explanations of how an algorithm works, code reviews and timed problem sets. Grading a full class's versions of the same assignment is slow, so experienced teachers build rubrics that score design choices and testing rather than only whether the program runs.

AP courses add outside deadlines. The AP Computer Science Principles exam has two parts, a through-course Create performance task in which each student develops a program of their choice and an end-of-course digital exam in May, so teachers schedule class time for the task and monitor submissions to the AP Digital Portfolio, which closes April 30 at 11:59 p.m. Eastern.

Standards changed too. The Computer Science Teachers Association published its 2026 CSTA PK-12 Computer Science Standards in summer 2026, the revision of its 2017 standards. Beyond the foundational progression, the new edition defines high school specialty standards at two levels in six areas: artificial intelligence, cybersecurity, data science, game development, physical computing and software development. A teacher asked to open a new pathway now has published standards for that area at both levels.

The job also includes running the lab. Laptops need charging, student accounts get locked, a district filter blocks the package site a lesson depends on, and a set of microcontrollers has to be counted back in before the bell. Teachers who test every tool on a student account before the unit starts lose fewer class periods to setup. The teacher may also serve as the building's informal computing expert, which can mean coaching a cybersecurity team after school or fielding questions from colleagues about classroom software.

The usual starting point is a bachelor's degree, either in computer science or a related field paired with a teacher preparation program, or in education with enough computing coursework to meet a state's content requirements. BLS describes career and technical education teachers, the occupation O*NET files this title under, as generally needing a bachelor's degree in the field they teach, with computer and information technology among its examples.

BLS notes that public school teachers may be required to hold a state-issued teaching certification or license, and the computer science piece of that license varies by state. Researchers mapping those routes for the American Society for Engineering Education found that paths to CS certification are similar to paths in other content areas, and that one of them is an add-on endorsement to another certification. Some states use the Praxis Computer Science (5652) test from ETS as the content exam; check the state education agency's list before registering, because each state sets its own test and passing score.

Student teaching is part of the standard route. BLS notes that all states require prospective career and technical education teachers in public schools to complete a supervised student-teaching placement with a mentor. Career changers from software jobs can look for a state alternative-route program, which typically lets a candidate teach on a provisional license while finishing coursework.

Technical skills that matter on the first day:

• Fluency in at least one text-based language used in class, plus comfort reading student code written in a block-based tool such as Scratch
• Enough data structures and algorithms to explain why a solution works, not only that it runs
• Practical lab administration: managing student accounts, cloud coding environments and device fleets
• Familiarity with the 2026 CSTA PK-12 standards and the state's own CS standards, which drive course maps and evaluations

Teaching skills carry as much weight. Running pair programming, writing debugging prompts that guide without giving the answer away, and designing projects that a beginner can finish and an advanced student can extend are learned on the job, and as a rough guide, expect two or three years of teaching a course before it runs smoothly.

Credentials that build a career include National Board Certification from the National Board for Professional Teaching Standards, and, for teachers of cybersecurity pathways, an industry certification such as CompTIA Security+. The Computer Science Teachers Association, which publishes those standards, also runs local chapters for teachers.

BLS does not project computer science teachers on their own. For career and technical education teachers as a group, the Occupational Outlook Handbook projects little or no change in employment from 2025 to 2035, with about 15,500 openings a year on average. A computer science opening exists only where a district has decided to offer, expand or require the subject, which makes state and district policy the thing to watch.

Code.org's 2025 State of AI + CS Education report finds that 60% of high schools offer foundational computer science and that access has plateaued, except in states with a computer science graduation requirement. The same report says overall participation declined slightly, especially in states that reduced computer science funding, and that small schools with fewer than 500 students face the greatest difficulty offering and sustaining the courses. Rural and urban schools, and schools with a high percentage of students receiving free meals, are less likely to offer computer science. A job seeker reading those figures may look first at larger districts and at states that have written computing into graduation rules. There is one encouraging line in the data for anyone building a program: young women's share of computer science participation rose from 32.5% the year before to 34% in 2024-25, according to the same report.

A 2025 landscape scan by the American Institutes for Research found that funding for teacher professional learning and clear computer science certification pathways were the two most common strategies states used or recommended to expand computer science education. The same scan noted that states more often have dedicated teaching certificates for upper grade levels than for elementary and middle school.

At the federal level, Executive Order 14277, signed April 23, 2025, directed the Secretary of Education to take steps to prioritize the use of AI in discretionary grant programs for teacher training authorized by the Elementary and Secondary Education Act. Code.org's report counts only 4 of 50 states that emphasize AI in their computer science standards and none that require AI plus computer science for graduation. In Code.org's framing, AI does not replace computer science but depends on it, and the report argues that education policy has to evolve along with computer science education.

In a public district, pay comes off the published salary schedule, with extra-duty stipends possible for coaching teams or running a department. Advancement inside education can lead to department chair, district computer science coordinator, instructional coach or curriculum writer. Some teachers move to state education agencies or nonprofit curriculum providers; others return to industry.

Dear Ms. Alvarez,

I am applying for the Computer Science Teacher opening at Lakeview High School. I hold a state teaching license with a computer science endorsement and have taught introductory programming and AP Computer Science Principles for three years at Ridgeway Middle-High School, where I also coach our cybersecurity team.

When I took over the introductory course, it was a sequence of syntax worksheets, and too many of my students stopped turning in work by October. I rebuilt the first semester around four short projects: a text adventure, a quiz game, a simple data dashboard built on our school's attendance data with names removed, and a final program each student designed. Every project had a beginner path and a stretch path, and students presented their code to a partner before submitting. Completion rose, and more of my students signed up for the AP course the next year.

For AP Computer Science Principles, I schedule the Create performance task in protected class blocks and hold short code conferences with each student before the submission deadline. Those conferences also answer the question every computer science teacher now faces about AI tools. My students may use an assistant for brainstorming and explanation, but they must walk me through every function they submit, and their version history has to show the work happening in class.

I would bring the same approach to Lakeview: projects that beginners can finish and stronger students can extend, clear rules on AI tools, and active recruiting of students who have never thought of themselves as programmers. I also maintain our lab of Chromebooks and microcontroller kits, so I am comfortable running the technical side of the classroom.

Thank you for your time. I would welcome the chance to teach a sample lesson.

Sincerely, Jordan Reyes
