拓展论文(英语：extended essay)简称 (EE) 是国际文凭大学预科课程(IB Diploma)里一个必须完成的核心项目。修读此文凭的学生需要根据自己的兴趣去进行探究和研究来独立完成一篇不多于4000字的学术论文(拓展论文)。 拓展论文和其他的核心项目一样，包括知识理论(Theory of Knowlege，简称TOK)课程和创意行动服务 (Creativity，Action，Service，简称CAS)，都必须由学生按时完成，否则不能取得IB文凭证书。

推荐的科目

虽然拓展论文是可以根据学生所选的题目而写的，但它还是推荐选择一些包括在IB课程而学生也有选读的科目领域内的题目(例如可以选择研究一本从未在IB英语课程内学习过的书本)。 可是，由于所选的题目必须要在4000字(英语)的限制内完成，因此不能于太过广泛或狭窄。此外，和题目有关的科目必须要由一位学校所属的老师以IB课程的方式来授教(因此能够确保会有拥有相应专业知识的老师来从旁指导学生)。而用来写拓展论文的科目(不是题目)，是被推荐选择一些学生一向都有选修的科目(虽然不一定要遵从)。另外，除非学生所写的题目是有关世界研究，否则EE是不能夸越多个科目，只能根据一个科目来写。However, some subjects include several disciplines, with an emphasis towards one. 例如社会学此科是能够包括化学，生物学，物理学等科目generally with an emphasis toward one discipline.

监督

The supervisor provides the student with assistance in putting together their EE, including guiding them in finding a suitable research question and on how to acquire the necessary resources to complete the research (such as a specific resource material–often hard-to-find documents or books–or laboratory equipment). The supervisor may suggest improvements to a version of the EE, but must not be engaged in writing it. The IBO recommends that the supervisor spend approximately two to three hours in total with the candidate discussing the EE. Some schools allow their students to choose a supervisor from outside their school, provided that the student appoint a teacher from inside the school to handle required administrative paperwork (such as anti-plagiarism policies).

评核

改制前

于拓展论文和知识理论能够取得的等级

Extended essays are marked by external assessors (examiners appointed by the IB) on a scale of 0 to 36. There are "general" and "subject-specific" criteria, at a ratio of 2:1 (24 possible marks for the general criteria and 12 marks for the subject-specific one). The total mark is converted into a grade from A to E. A similar system is used for theory of knowledge and students can gain up to 3 points for the diploma based on the grades achieved for EE and TOK. Prior to the class of 2010, a diploma candidate could receive a failing grade in either the extended essay or theory of knowledge and still be awarded a diploma. However, if a student scores an E on either the extended essay or TOK essay post-2010, he or she will only be eligible to receive an IB diploma if 28 points are achieved overall.
