IB vs A-Level: A Complete Guide to University Success
IB vs A-Level: Discover which diploma sets you up best for university acceptance, higher grades, and better career prospects, based on HESA student data.
We know this is a controversial question to ask – IB students take pride in the difficulty in the diploma and A Level students are no different. For those of you who are unaware of A Levels, they are the common path that students in the UK follow. As former IB students, though, we wanted to see if we could find some real answers about what really sets you up for university best, though… Is it the infamous IB programme or the classic A Level Diploma? Let’s take a look at the facts!
Note: The following is based on a study conducted by the Higher Education Statistics Agency (HESA) in 2016. To read the full study, follow this link.
Who gets accepted to the best universities?
40.1% of IB students were accepted to a Top 20 Higher Education provider in the UK (based on an index created by looking at 3 major university ranking lists), while the same number only stands at 23.7% for A Level Students. So, it would suggest that IB students are more likely to be accepted to one of the top universities in the UK.
Which courses are IB Diploma and A Level students likely to study?
A few fields that a higher proportion of IB students go into than A Level students include Medicine, Engineering & Technology, Business & Administrative Studies, and Law. A Level students, on the other hand, are more likely to go into fields such as Biological Sciences, Physical Sciences, Creative Arts & Design, and Education.
While a few of these fields show stark differences in the proportion of IB and A Level students, most fields are relatively similar – so it’s difficult to draw any real conclusions about the likelihood of being accepted to a certain course based on your diploma.
Who is most likely to drop out of university?
The study followed up with IB and A-Level students after 1 year at university to see what proportion of students continue and make it into their second year. A whopping 93.2% of IB Diploma students continued at university after one year, while this number stands at 92.8% for A Level students. It’s difficult to tell if this difference is statistically significant, so in this regard A Level and IB students may be considered similar!

Who gets the best grades at university?
A quarter of IB students (24.4%) graduate their higher education with a first class degree, the highest degree classification possible in the UK. This number falls to a fifth (20.7%) for A Level students. Naturally, A Level students are thus more likely than IB students to an upper second class, lower second class, or third class degree.
Who gets the best jobs?
Proportionally, A Level students are more likely to have their first job out of higher education be within the fields of Wholesale and Retail Trade, Accommodation and Food Service, Education, or Transport and Storage. IB students are more likely to work within Scientific & Technical Activities, Information and Communication, or Financial and Insurance Activities.
Who makes the most money?
The median salary of an IB graduate the year after leaving Higher Education stood at £21,000 in 2012. For A Level students this number stood at £20,000, so not a large difference, but a statistically significant one. This naturally comes due to IB students being proportionally slightly more likely to work within fields such as medicine, sciences, and finance, where the base salary is typically higher than industries like wholesale, retail, or service.

Remember that although statistics only show general trends they aren’t guarantees that you’re going to get accepted to the best universities and get the highest paying job just because you’re doing the IB Diploma! Keep working hard and you’ll reap the rewards in just a few short years!

Why Lanterna?
According to a HESA study, IB students show several advantages. They are more likely to be accepted into top UK universities, achieve first-class degrees, and pursue careers in higher-paying fields like Medicine, Engineering, and Finance, leading to slightly higher median salaries post-graduation.
Yes, the HESA study found that 40.1% of IB students were accepted into a Top 20 UK Higher Education provider, compared to 23.7% of A-Level students. This suggests IB students have a significantly higher likelihood of gaining admission to top institutions.
The study indicates that IB students are more likely to achieve higher academic results at university. A quarter of IB students (24.4%) graduated with a first-class degree, compared to a fifth (20.7%) of A-Level students.
IB students show a higher propensity to enter fields such as Medicine, Engineering & Technology, Business & Administrative Studies, and Law. This aligns with the broad and rigorous nature of the IB Diploma, which prepares students for diverse and challenging academic paths.
The HESA study reported that the median salary for an IB graduate one year after leaving higher education was £21,000, compared to £20,000 for A-Level students. This statistically significant difference is attributed to IB students entering proportionally more high-earning fields.
While the study found similar retention rates after the first year (93.2% for IB vs. 92.8% for A-Levels), the higher proportion of IB students achieving first-class degrees suggests that the IB Diploma's emphasis on independent learning, critical thinking, and research skills may better equip them for sustained academic success at university.
