In comparing US bachelor's degrees to British honours degrees, equivalencies can be expressed in terms of either US Grade Point Averages (GPAs) or letter grades. British institutions normally state equivalence in terms of GPAs. Approximate mappings between British classifications and GPAs can be inferred from the graduate admissions criteria used by British universities, which often give international equivalents. For example, University College London (UCL) equates the minimum classification for entrance to GPAs using 2:1 = 3.3 and 2:2 = 3.0. Different universities convert grades differently: the London School of Economics and Political Science (LSE) considers a GPA of 3.5 or better as equivalent to gaining a 2:1, while the department of English Language and Literature at Oxford considers a GPA of "about 3.8" equivalent to a first class degree. Similarly, the UK NARIC gives equivalent GPAs for determining eligibility for teacher training bursaries. Durham University's "North American Undergraduate Guide" gives a conversion table as a guide to understanding British classifications (rather than for admission to postgraduate study) of 1st = 3.8–4.0, 2:1 = 3.3–3.7, 2:2 = 2.8–3.2 and 3rd = 2.3–2.7.
