Given the task definition and input, reply with output. In this task, you are given a set of context paragraph and some supporting facts to answer a question. Your task is to generate answer for given question based on set of context paragraphs and supporting facts.

Context_1 : Ability to benefit (ATB) is a term used in the context of post-secondary education in the United States to refer to students who have sufficient competency to benefit from post-secondary education but do not have a high school diploma or the Certificate of High School Equivalency. ATB, as assessed by government-approved tests, is required for receiving financial aid by most US public colleges that admit students without a high school diploma or the certificate of equivalency. Until July 2012, such students could also receive student loans and grants from the US government if they had passed an approved ATB examination. However, the provision was dropped as part of the cuts to the Federal budget for fiscal year 2012. Context_2 : Anishinabek Educational Institute (AEI) is an Aboriginal-owned and controlled post-secondary institution. Aboriginal institutes partner with colleges and universities to offer students degree programs, apprenticeships, certificate programs and diploma programs. AEI was founded to provide greater access to post-secondary education for Aboriginal peoples. AEI delivers post-secondary programs approved by the Ministry of Training, Colleges and Universities. The educational curriculum was adapted to meet the needs of Aboriginal learners to ensure it reflects community needs, cultural heritage and identity. AEI is a strong advocate of lifelong learning - evident in its initiatives to raise Aboriginal student entry into post-secondary education through educational programs offered at the elementary and secondary level. Context_3 : A vocational school, sometimes called a trade school or vocational college, is a type of educational institution, which, depending on country, may refer to secondary or post-secondary education designed to provide vocational education, or technical skills required to perform the tasks of a particular and specific job. In the case of secondary education, these schools differ from academic high schools which usually prepare students who aim to pursue tertiary education, rather than enter directly into the workforce. With regard to post-secondary education, vocational schools are traditionally distinguished from four-year colleges by their focus on job-specific training to students who are typically bound for one of the skilled trades, rather than providing academic training for students pursuing careers in a professional discipline. While many schools have largely adhered to this convention, the purely vocational focus of other trade schools began to shift in the 1990s "toward a broader preparation that develops the academic" as well as technical skills of their students. Context_4 : Undergraduate education is the post-secondary education previous to the postgraduate education. It includes all the academic programs up to the level of a bachelor's degree. For example, in the United States, an entry level university student is known as an undergraduate, while students of higher degrees are known as graduates. In some other educational systems and subjects, undergraduate education is post-secondary education up to the level of a master's degree; this is the case for some science courses in Britain and some medicine courses in Europe. Context_5 : The Porter School of Environmental Studies (PSES) is an independent graduate school within Tel Aviv University. It is Israel's first graduate school to focus on research, teaching and the sharing of environmental knowledge, and one of the few worldwide to take a multidisciplinary and interdisciplinary approach to the study of environmental issues. Context_6 : The Queen's School of Environmental Studies is a unit of the Faculty of Arts and Science at Queen's University in Kingston, Ontario, Canada. The school offers an interdisciplinary approach to undergraduate and graduate studies dealing with the environment. Context_7 : The Millennium Research Program of the Canada Millennium Scholarship Foundation was launched in 2001 to assist the Foundation in carrying out its mandate to improve access to post-secondary education in Canada and provide students with the educational opportunities they need to prepare themselves for the future. The Research Program advances the study of barriers to post-secondary education and the impact of policies and programs designed to alleviate them. It ensures that policy-making and public discussion about opportunities in higher education in Canada can be informed by rigorous analysis and empirical evidence. Context_8 : The Higher Education Research Institute (HERI) serves as an interdisciplinary center for research, evaluation, information, policy studies, and research training in post-secondary education. HERI is housed in the UCLA Graduate School of Education and Information Studies (GSE&IS) at the University of California, Los Angeles. The Institute's research program covers a variety of topics including the outcomes of post-secondary education, leadership development, institutional transformation, faculty performance, federal and state policy, and educational equity. Context_9 : Environmental studies is a multidisciplinary academic field which systematically studies human interaction with the environment in the interests of solving complex problems. Environmental studies brings together the principles of the physical sciences, commerce/economics and social sciences so as to solve contemporary environmental problems. It is a broad field of study that includes the natural environment, the built environment, and the sets of relationships between them. The field encompasses study in basic principles of ecology and environmental science, as well as associated subjects such as ethics, geography, anthropology, policy, politics, law, economics, philosophy, sociology and social justice, planning, pollution control and natural resource management. There are also many degree programs in Environmental Studies including the Master of Environmental Studies and the Bachelor of Environmental Studies. Context_10 : The formation of a Commission on the Future of Higher Education, also known as the Spellings Commission, was announced on September 19, 2005, by U.S. Secretary of Education Margaret Spellings. The nineteen-member commission was charged with recommending a national strategy for reforming post-secondary education, with a particular focus on how well colleges and universities are preparing students for the 21st-century workplace, as well as a secondary focus on how well high schools are preparing the students for post-secondary education. In the report, released on September 26, 2006, the Commission focuses on four key areas: access, affordability (particularly for non-traditional students), the standards of quality in instruction, and the accountability of institutions of higher learning to their constituencies (students, families, taxpayers, and other investors in higher education). After the report's publication, implementation of its recommendations was the responsibility of U.S. Under Secretary of Education, Sara Martinez Tucker (appointed August 2006). fact_1 : The school offers an interdisciplinary approach to undergraduate and graduate studies dealing with the environment. fact_2 : Undergraduate education is the post-secondary education previous to the postgraduate education. Question: The Queen's School of Environmental Studies offers an interdisciplinary approach to the post-secondary education that is previous to what?
postgraduate education
