The following findings by eminent academics are as follow:
1. “How Central Exams Affect Educational Achievement: International Evidence from TIMSS and TIMSS-Repeat” by Ludger Woessmann (2002) of John F Kennedy School of Government, Harvard University
The data used in the paper are sourced from the Third International Mathematics and Science Study (TIMSS; 1994-1995) and the TIMSS-Repeat (1998-1999) covering 40 nations. They include performance data in both math and science for about 450,000 students, as well as background data on families, school resources and institutional setting for individual students, teachers and schools.
This study showed that “students in countries with central exit-exam systems perform 35 to 47 percent of an international standard deviation in test scores better in their middle-school years in both mathematics and science than students in countries without central exams.”
2. “The Effect Of Central Exit Examinations On Student Achievement: Quasi-Experimental Evidence From TIMSS Germany” by Hendrik Jürges & Kerstin Schneider & Felix Büchel, 2003.
This paper makes use of the regional variation in schooling legislation within the German secondary education system to estimate the effect of central exit examinations on student performance. The study concluded that “students in federal states with central exit examinations clearly outperform students in other federal states” although they did qualify that part of the difference could be attributable to other factors.
3. “Are National Exit Examinations Important for Educational E?ciency?” by John H. Bishop (1999), Cornell University
Students in countries with national exit exams exams tend to outperform students in other countries in science, math, reading, and geography, when national economic development levels are accounted for.
A study of the elimination of the Swedish exit examination system in the 1970s, in combination with changes in the way university applicants were selected, also “appears to have led to a decline in the number of upper secondary school students taking rigorous courses in mathematics and science.”
This study covered extensively data sourced from (i) TIMSS, (ii) the reading literacy of 14 year olds in the International Association of the Evaluation of Educational Achievement's (IEA) Reading Study, Science, (iii) math and geography scores of 13 year olds on the International Assessment of Educational Progress (IAEP) for 16 nations and (iv) Science and math scores of 13 year olds in nine Canadian provinces.
4. “The Effect of National Standard and Curriculum-Based Exams on Achievement” by John H. Bishop (1997)
In this study, Bishop concluded that “our review of the evidence suggests that the claims of the advocates of standards and examination based reform of American secondary education my be right. The countries and Canadian provinces with such system outperform other countries at comparable levels of development.
This study also looked at the (i) TIMSS data, (ii) the International Assessment of Educational Progress 1991 covering 15 nations including England, Switzerland, Taiwan and Korea and (iii) the Canada IAEP 1990-91 with data from more than 1,400 schools.
Studies which provides contrary conclusions are few and far in between and often focuses on the negative impact of excessive stress on a student while accepting that a moderate amount of stress for the students is beneficial in terms of student achievement.
Given the above studies, I'll like to reiterate my earlier assertion that it is the nature of examinations and teaching methods which will determine the quality of student achievements and not the fact as to whether examinations are abolished.
Even if the UPSR and PMR is abolished, but the nature of the Form 5 SPM examination as well as the teaching methods and quality remains unchanged, then the student output from our education system will remain little changed from what it is today. In fact, the removal of examinations may disincentivise students, particularly from the lower income groups as well as from families with lower educational qualifications to fare worse than before due to the lack of uniform achievement standards.
