I've follow the design process, in particular to the algorithm proposed. But I am still horribly confused. WHAT IS THE NEW ASSIGNMENT ALGORITHM?<br /><br />I've garnered these pieces:<br /><br />1. SFUSD's priority<br />http://sfusd.ggnet.net/next-year/faqs.php#tie-breakers<br /><br />2a. Muriel's powerpoint (slide 20)<br />http://www.stanford.edu/~niederle/SFUSDBoardPresentationFeb.17.2010.pdf<br /><br />2b. Top trading cycles as in the Boston Public School Match paper<br />http://kuznets.fas.harvard.edu/~aroth/papers/bostonAEAPP.pdf<br /><br />2a and 2b look rather different to me. In additional 2a's trading take both school and student's preference into account. But Muriel's transfer process (slide 17-19) seems to take only students preference into account. Another question is on Muriel's slide 20 point #1, it says "highest preference". But the term seems to be ambiguous. Is it highest preference to the student or to the school?<br /><br />The press and the public seems to mostly concern about the priority list of 1. No one seems to care or understand what the assignment (e.g. 2a or 2b) process is really like. Can you tell me what exactly is the assignment process?<br /><br />The SFUSD's FAQ is also confusing.<br /><br /><i> <br />Point 6: If you do not get one <br />of your choices, you will be<br />offered your attendance area <br />school if it has openings.<br />Otherwise you will be offered <br />the school closest to your <br />home with openings.<br /></i><br /><i> <br />Note: If these tie-breakers <br />do not resolve ties, then ties <br />will be resolved by random <br />lottery.<br /></i><br /><br />It implies the priority matching mechanism in the Boston paper that you say should not be used. I think SFUSD people are as least as confused as I'm.<br /><br /><br />@KWillets, good observation !Tung Wai Yiphttps://www.blogger.com/profile/01409046343777567728noreply@blogger.comtag:blogger.com,1999:blog-4748060798655400108.post-16518458837276426932010-10-06T11:30:22.220-07:002010-10-06T11:30:22.220-07:00I've looked this over in more detail, and it a...I've looked this over in more detail, and it appears that there is a huge amount of regional bias in the TTC mechanism. When all other factors are equal, a student in a popular school is more likely to get a TTC trade than a student in an unpopular school. So students living near popular schools not only have priority there, but also at other schools.KWilletsnoreply@blogger.comtag:blogger.com,1999:blog-4748060798655400108.post-1524984984328853312010-10-03T13:59:02.205-07:002010-10-03T13:59:02.205-07:00A few questions (I will likely have more) -- When ...A few questions (I will likely have more) -- When two kids want the same Top Trading Cycle, is the lottery number used to rank them? <br /><br />At what point do the parents have to rank all the schools (I saw a mention of later rounds)?KWilletsnoreply@blogger.comtag:blogger.com,1999:blog-4748060798655400108.post-89737042160769573692010-09-29T16:55:28.061-07:002010-09-29T16:55:28.061-07:00will any of the parent programers or designers on ...will any of the parent programers or designers on this project who were excluded by the action of the school district contact me off list?
