GED vs High School Diploma vs A Levels vs IB: What Is the Difference?
By William Cognity · 1 November 2026 · 3 min readFamilies often ask which qualification is best. The honest answer is that it depends on the country, the course and the student. Here is a simple comparison.
High school diploma
A diploma is awarded by a school after several years of study. It is the usual route in the United States and many other countries.
GED
The GED is a US high school equivalency credential, based on four subject tests. It is a route for people who did not finish high school. Many US colleges accept it.
A Levels
A Levels are subject-based qualifications, often three subjects. UK and many international universities use them for offers.
IB Diploma
The IB Diploma is a two-year course with six subjects plus Theory of Knowledge, the Extended Essay and CAS. Many universities worldwide recognise it.
How to choose
- Start with the course and the countries you want.
- Check each university's entry page.
- Think about how you learn: exams, coursework, or a mix.
- If you missed a stage, ask which route lets you catch up.

Questions
Which is hardest?
They are hard in different ways. Judge by fit, not by reputation.
Do universities treat them equally?
Not always. Each university has its own rules. Check before you choose.
Can I switch routes?
Sometimes. Ask early, because credits do not always transfer.
