How to Switch to a Career in Software Development From Teaching

How Your Background Transfers

Two teaching backgrounds transfer in different, concrete ways.

High school math or science teacher. Your degree is the headline. BLS says software developers typically need a bachelor's degree in computer and information technology or a related field such as engineering or mathematics (U.S. Bureau of Labor Statistics, 2025) — a mathematics or physics degree is already in that stated family, and you can say so directly on your résumé. Day to day, the work you already do maps onto what ONET lists as transferable skills for software developers: Systems Analysis, Complex Problem Solving, Judgment and Decision Making, Time Management and Coordination (ONET OnLine, 2026). Breaking a unit into prerequisite steps is systems analysis. Diagnosing why a student's method fails on one problem type is debugging. Mathematics is also listed as one of four knowledge areas for the occupation, alongside Computers and Electronics, Customer and Personal Service, and English Language (O*NET OnLine, 2026).

Special education or ELL teacher. Your credential-level skill is documentation under rules. Writing IEP goals, tracking progress data against measurable criteria, and defending that documentation in a meeting is the same muscle as writing test cases, logging defects with reproduction steps, and maintaining an audit trail — which is why QA analyst and tester roles, grouped with developers by BLS, are a common first landing spot. Your state-issued teaching certification or license (U.S. Bureau of Labor Statistics, 2025) does not transfer as a technical qualification, but the compliance habits behind it do.

All classroom teachers. BLS names communication as an important quality for these workers specifically because they must give clear instructions, explain problems to team members, and explain to nontechnical users such as customers how the software works (U.S. Bureau of Labor Statistics, 2025). You have spent years explaining abstract systems to people who did not ask for the explanation. Say that in interviews with an example, not as an adjective.

What does not transfer: classroom management, your years of service, and your license. Employers will want code they can read.

Your Transition Timeline

Realistic range: 12 to 24 months from first lesson to first offer if you stay in the classroom while you learn, and roughly 9 to 15 months if you study full-time through a summer and the following year. Below is a part-time sequence built around the school calendar.

Months 1–3: pick one language and prove you will stick with it. Milestone: 150 logged hours of practice and one small working program in a public Git repository. No credential yet. Cost: community college introductory programming courses are priced per credit hour, and that rate varies by state and district — check your local college's published per-credit tuition. Self-study materials can be free.

Months 4–9: a credential plus two real projects. Milestone: pass a named certification and ship two applications other people can use. For an IT support or help-desk entry route, CompTIA A+ requires passing both Core 1 (220-1201) and Core 2 (220-1202), each with up to 90 questions in 90 minutes, scoring 675 on Core 1 and 700 on Core 2 (Capstone Workforce Solutions). CompTIA publishes the retail price per exam and the number of exams required (CompTIA, 2024) — budget from their current published price list, and remember that is a per-attempt fee.

Months 10–15: cloud or vendor credential and your third portfolio piece. Milestone: a deployed application and a vendor certification. BLS notes that programmers may become certified in specific programming languages or vendor-specific products, and some companies require certification in the products they use (U.S. Bureau of Labor Statistics). The AWS Certified Developer – Associate (DVA-C02) is one such option; AWS publishes the exam cost, question count, duration and passing score (DataCamp), and the credential carries a defined validity period with a recertification path (DataCamp), so check AWS's own certification pages before paying.

Months 16–24: applications, interviews, and the first job. Milestone: a signed offer and the start of on-the-job training, which BLS lists as typically needed to attain competency in this occupation group (U.S. Bureau of Labor Statistics, 2025). Cost in this phase is mostly unpaid time: 6 to 10 hours per week on applications, take-home assignments and interviews. Employment of software developers is projected to grow over the decade (U.S. Bureau of Labor Statistics, 2024), but growth is not a hiring guarantee for any individual.

Step-by-Step: Making the Switch

1. Audit your degree against the stated requirement. BLS names computer and information technology or a related field such as engineering or mathematics, with some employers preferring a master's (U.S. Bureau of Labor Statistics, 2025). One evening. If your degree is in education or a humanities field, plan to compensate with certification and portfolio depth rather than a second bachelor's.
2. Commit to one language and one stack for 12 months. 8–10 hours a week. Switching languages every two months is the most common reason a teacher's portfolio still looks empty at month 12.
3. Build three portfolio projects, not twenty tutorials. Aim for roughly 40–80 hours each: one that reads and writes data, one that calls an external service, one deployed at a public URL with a README explaining the design decisions. Cost: domain and hosting fees, which vary by provider.
4. Sit a named certification. For a support-to-developer route, CompTIA A+ requires two exams, Core 1 (220-1201) and Core 2 (220-1202), with passing scores of 675 and 700 (Capstone Workforce Solutions) — a measurable difference from a single-exam cloud credential such as AWS Certified Developer – Associate (DVA-C02), which is one sitting (DataCamp). Two exams means two fees and two study blocks; price both from the issuing bodies' current published rates before choosing.
5. Do eight informational interviews. 30 minutes each, free. Ask working developers which language their team hires for locally and what their junior hires' portfolios contained. Local user groups and your district's IT staff are the easiest first contacts.
6. Write and rehearse your career-change explanation. Hiring managers will ask. Give them a reason rooted in the work, and a date.

Why I left teaching, in an interview

"I taught high school algebra for seven years. The part of the job I was best at was taking a system apart and sequencing it so someone else could follow it — which is what pulled me into building software. I started writing Python in January 2024, shipped three applications you can run from my repository, and passed CompTIA A+ Core 1 and Core 2. I want to do that full-time on a team."

1. Apply to QA analyst, technical support and junior developer roles in parallel. BLS groups developers, QA analysts and testers together (U.S. Bureau of Labor Statistics, 2025), and a QA seat gets you inside a release process. Budget 6–10 hours a week for three to six months of applications.
2. Keep your teaching license current while you search. Renewal rules and lapse periods are set by each state's education agency — check yours, not a forum, before letting anything expire.

• You have passed your chosen certification — for CompTIA A+, that means both Core 1 (220-1201) and Core 2 (220-1202), at 675 and 700 respectively (Capstone Workforce Solutions) — or you have a booked exam date.
• You have checked your state education agency's rules on teaching licence renewal and lapse, and written down the date yours expires.
• You have read your teaching contract's resignation notice clause and the date after which you cannot resign without penalty.
• You have completed at least eight informational interviews with working developers or QA analysts.
• You have delivered your career-change explanation out loud in at least three of those conversations.
• You have completed at least two technical screens or take-home assignments.
