<p>tsdad: I'm not sure I agree that going through the IB primary and middle years programs is necessarily the best preparation for the IB diploma program.</p>
<p>The problem here is that the programs for younger students are designed for ALL students, while the diploma program is intended only for those who are university-bound. There is a level of rigor in the diploma program that would not be appropriate for the younger students' programs because the younger students' programs must be designed so that all can succeed, while it is openly acknowledged that some students are not suitable candidates for the diploma program.</p>
<p>Much depends, of course, on the population of students in the school and how the school approaches the IB curriculum. </p>
<p>The suburban high school that my daughter attended, and its feeder middle school, actually had the IB middle years program available as an option. Some 11th and 12th grade students in the IB diploma program came from that program, while others came from two years of special pre-IB preparation in 9th and 10th grades, with no exposure to IB before that. The general consensus among the kids was that the students from the middle years program were not as well prepared for the diploma years as those who had gone through the locally designed 9th and 10th grade prep years because the middle years program was less rigorous.</p>
<p>But of course, this reflects the experience of only one school. Other schools may have different experiences. A private school that serves a population where all are very capable academically could probably develop a seamless and very rewarding IB program for the full 12 grades.</p>
<p>Christcorp, I wish I had gone to your high school. My high school education of thirtysomething years ago was not as good as what my kids received (both the one in IB and the one who went to a regular high school). </p>
<p>Xiggi, I think we should judge the merits of a school system by how well it meets the needs of all of its students. Assessing a school system ONLY on the basis of how well it raises the common denominator to a reasonable level is not enough. Neither is assessing the system ONLY on the basis of the opportunities it offers for its best students to go as far as their abilities will take them. Both of these things, and many more, should be incorporated into the definition of success.</p>
<p>Also, Xiggi, if there is one thing IB is NOT, it's a mile-wide, inch-deep curriculum. In fact, IB is known for having more depth and less breadth than AP. </p>
<p>Kids who have taken AP exams will tell you that in order to succeed on many of them, you have to have memorized vast amounts of trivia and be able to answer extremely picky multiple-choice questions. </p>
<p>IB exams are different. Most of them are entirely or mostly essay tests, and the students have choices of which essay topics to write about. It's the depth and organization of what the student has to say about the chosen topics that serve as the basis for the exam grade.</p>
<p>You can compare, for example, IB versus AP history tests. The two have one thing in common: both include a document-based question. Beyond that, the tests are very different. The rest of the IB exam is ALL essay (five hours of essay writing for HL). Most of the rest of the AP exam is multiple-choice (although I think there is one additional essay). Thus, the two tests are two very different experiences.</p>
<p>In addition, IB "exam" grades are never based solely on a single written exam. There are always other elements included -- projects completed as class assignments (technically called internal assessments or external assessments -- IAs or EAs, and it is not important to understand the difference between the two), and sometimes one-on-one oral testing as well. How well the student performs on these other assessments is incorporated into the "exam" grade. This is why you can take an AP test without having taken the course, but you cannot do the same with an IB test.</p>
