In almost every country, teaching in a state school requires a university degree, a period of supervised classroom practice, and a government license or registration. The packaging differs: a four-year Bachelor of Education, a subject degree plus a training year like England's PGCE, or a master's degree as in Finland. Private and international schools sometimes hire without local licensure, but the degree requirement is nearly universal.
Typically four to six years after secondary school: a three- or four-year degree, one to two years of teacher training and supervised practice, then a probation or induction period of one to two years before full licensure. Finland's standard route runs about five to six years because a master's degree is mandatory; some fast-track programs place career changers in classrooms within months, with training alongside.
It varies more by country than almost any comparable profession. Luxembourg's statutory scales, the OECD's highest, climb above €120,000; German teachers commonly earn €55,000–€85,000 with civil-servant status; the US average was about $72,000 in 2023–24 per the NEA; England's main scale ran roughly £32,000–£49,000 in 2024–25; and low-fee private schools in India may pay under ₹20,000 a month.
UNESCO estimated in 2023 that the world needs 44 million additional teachers by 2030, about 15 million of them in sub-Saharan Africa, where student numbers are growing fastest. In wealthier countries the problem is attrition and recruitment rather than demographics: roughly 8% of US teachers leave the profession each year, and shortages concentrate in physics, mathematics, computing and special education.
Parts of the job are already automating: routine grading, drafting worksheets, drill practice and administrative reporting. But the core of classroom teaching — motivating thirty real children, managing behavior, noticing which quiet pupil stopped understanding on Tuesday, and carrying legal safeguarding duties — has no automated substitute. Most systems are deploying AI tutors as a homework layer under a human teacher, not in place of one.
The Varkey Foundation's Global Teacher Status Index, which surveyed 35 countries in 2018, ranked China first — respondents there compared teachers to doctors — with Malaysia and Taiwan close behind, while several European countries ranked teachers nearer to social workers or librarians. Finland is the standard case where selectivity drives prestige: primary-teacher programs admit roughly one applicant in ten and require a master's degree.
Teaching is licensed almost everywhere, but the gate sits in different places. Finland filters at university admission — its class-teacher programs take roughly one applicant in ten and end in a master's degree. Korea and Japan filter at the employment exam, after the degree. The United States filters weakly at both ends and instead loses a large share of entrants in the first five years on the job. Where the filter sits shapes who ends up in front of children.
The common skeleton underneath is fixed: subject knowledge, formal study of teaching, a supervised practicum in a real classroom, a state license, then an induction or probation period. What follows maps that skeleton and the main national variants — and the two genuinely different doors in: fast-track programs like Teach For America and Teach First, and mid-career lateral entry.
Either a Bachelor of Education combining subject study with pedagogy, or a pure subject degree (mathematics, history, a language) followed by separate teacher training. Secondary teaching nearly always requires depth in the subject to be taught.
The filterUniversity admission — decisive in Finland, where class-teacher programs admit roughly 10% of applicants via exams and interviews.
Formal training in pedagogy, child development, assessment and curriculum: England's PGCE, a US master's or credential program, Germany's university teacher-education track, Finland's mandatory research master's.
The filterProgram admission, subject-knowledge tests, and criminal-background clearance for work with children — required in virtually every system.
Supervised teaching in a real school under a mentor teacher, planning and delivering real lessons with observation and feedback — the stage trainees consistently call the true beginning of learning the craft.
The filterSign-off from the supervising mentor and university tutor; failing the practicum ends most candidacies regardless of grades.
The state's stamp: Praxis or edTPA exams plus state certification in the US, Qualified Teacher Status in England, the First State Examination in Germany, prefectural teaching licenses in Japan, Korea's national teacher employment examination.
The filterThe exam itself — in Korea, the 임용시험 regularly passes only a fraction of candidates, making a public-school post harder to win than many corporate jobs.
Teaching a real timetable under structured mentoring and formal review: England's two-year Early Career Teacher induction, Germany's Referendariat ending in the Second State Examination, probationary years in most US districts and Japanese prefectures.
The filterProbation sign-off — an unsatisfactory induction judgment can bar a teacher from the state system entirely.
Head of department, curriculum lead, special-education specialization, National Board Certification in the US, England's National Professional Qualifications, or the leap to assistant principal and principal — plus mandatory continuing professional development nearly everywhere.
The filterAdvanced certification exams, leadership qualifications and competitive internal appointment; in East Asia, seniority-plus-examination systems govern promotion.
In Finland and Germany, teacher education is tuition-free and Germany pays trainees a salary through the Referendariat; England charges around £9,250 a year in tuition but offers tax-free bursaries up to about £28,000 (2024–25) in shortage subjects like physics. In the United States, a bachelor's degree plus certification commonly costs $40,000–$80,000 or more — a debt load frequently cited in studies of why American teaching struggles to recruit.
Combines child development, pedagogy and curriculum with embedded school placements; the standard door into primary teaching in most countries and the largest single source of new teachers worldwide.
A degree in mathematics, physics, history, English or a language, followed by a training year. Secondary systems increasingly require genuine subject depth — England pays tax-free bursaries up to about £28,000 (2024–25) to lure physics and maths graduates.
A distinct specialization covering play-based learning, language acquisition and developmental assessment, tracing to Froebel's kindergarten; demand is rising as governments expand pre-primary provision worldwide.
Training in disability, inclusion, individualized education plans and behavior support. Special-education posts go unfilled in the US, England and Australia year after year, making it the closest thing teaching has to a guaranteed-employment major.
Educational psychology underpins assessment and learning science; linguistics feeds language teaching and TESOL certification — the qualification behind the global English-teaching market that employs hundreds of thousands of graduates abroad.
The flagship of the world's most-studied teacher-education system: research-based master's degrees required for all class teachers, with admission rates around one in ten.
Founded 1902 and still carrying the école-normale name; China's leading teacher-education institution, feeding the school system of the country ranked first for teacher status in the 2018 Varkey index.
London's dedicated education faculty, repeatedly ranked the world's top institution for education in the QS subject rankings and a major PGCE provider for England's schools.
Founded 1887, the first and largest US graduate school of education; John Dewey taught there, and it shaped progressive education across the Americas and East Asia.
Korea's most prestigious route toward the fiercely competitive national teacher employment exam, in a system where public-school teachers hold civil-servant status.
Descended from the Tokyo Higher Normal School founded in 1872, the first year of Japan's modern school system; still a central institution in Japanese teacher education and curriculum research.
The Ontario Institute for Studies in Education, one of North America's largest education faculties and a consistent top-five presence in global education rankings.
One of the southern hemisphere's leading education schools, training teachers for Australia's state systems and a large international cohort across Asia-Pacific.
The legal license to teach in English maintained schools, awarded after accredited training and assessment against the national Teachers' Standards, followed by a statutory two-year Early Career Teacher induction with mentoring and reduced timetable.
Licensure is state-by-state: an approved preparation program plus examinations — commonly the Praxis series or the edTPA portfolio — with certificates specific to grade band and subject. Reciprocity between states is partial, a standing complaint of mobile teachers.
A teaching certificate alone does not grant a public-school job in Korea: candidates must also pass the annual national employment exam, whose written papers, essay and demonstration lesson admit only a fraction of takers to civil-servant teaching posts.
German teachers pass a First State Examination after university, then an 18-to-24-month salaried Referendariat of supervised school practice ending in the Second State Examination — after which most are appointed as Beamte, tenured civil servants.
Founded in 1990 in the US and copied in London in 2002, these place high-achieving graduates in shortage schools after summer training, with certification earned on the job; the Teach For All network now spans over 60 countries. Retention beyond the initial commitment remains their most-debated statistic.
Most systems now run alternative certification for career changers — engineers into physics classrooms, accountants into mathematics — through routes like US alternative-route programs, which supply roughly a fifth of new American teachers, and vocational schools worldwide hiring industry professionals to teach their trade.
