ISL High School Diploma

ISL offers a fully recognised US High School Diploma in addition to the International Baccalaureate (IB) Diploma, as ISL is accredited by the New England Association of Schools and Colleges (NEASC).

The IB Diploma and the ISL High School Diploma are two separate qualifications. The IB Diploma is a more demanding programme, and students who successfully complete it are also awarded the ISL High School Diploma.  However, several students each year choose to focus their efforts on achieving the ISL High School Diploma only, rather than both qualifications simultaneously. Achieving greater success with a reduced range of courses that meets the requirements of the ISL High School Diploma is the correct choice for a number of our students. It involves taking individual courses that lead to the same final IB examinations, and results in a portfolio of official IB course results that are recognized by universities in combination with the ISL High School Diploma.

The ISL High School Diploma is sufficient for entry into 4-year universities in both the US and Canada, as well as US-style universities located in different parts of the world. If a student is interested in studying in the UK, then a foundation programme will be necessary after graduating from High School.

The requirements of the ISL High School Diploma

The course requirements for graduation with the ISL High School Diploma are as follows:

  • 4 years of a first language;
  • 4 years of mathematics;
  • 4 years of science;
  • 4 years of social science;
  • 2 years of a second language;
  • Completion of the Creativity Activity and Service (CAS) programme.

In order to receive an ISL High School Diploma, students must achieve an average grade of 3.0 or above in each individual subject, each academic year of High School (taken as an average of the two semester reports).

Students who do not meet this requirement in an individual subject, but who are awarded a grade of 3.0 or above by the IB in that subject following the final IB Diploma Programme (DP) examinations, will receive an ISL High School Diploma awarded in July of their graduation year.

A High School Certificate is awarded to any students who do not meet the requirements of the ISL High School Diploma.

*An N is assigned by the IB when a grade is not possible due to requirements not being met - for example, when a subject component has not been submitted.

Summary of the advantages of an ISL High School Diploma over the IB Diploma

  • No requirement to take TOK;
  • No requirement to complete the extended essay;
  • Students can take 5 subjects rather than 6;
  • No requirement to take subjects at HL;
  • No requirement to meet the exacting standards of the IB Diploma (24 points in total across the subjects, no less than 12 points total in HL subjects, etc);
  • Additional study periods provide extra time to devote to challenging subjects;
  • As indicated above, a range of university and college options remain open with the ISL High School Diploma, and the academic counselling team is well able to advise on these options. They can also provide examples of a number of alumni who have successfully benefited from taking the ISL High School Diploma.
