Amsterdam school choice: next year will be single tie-breaking deferred acceptance (instead of multiple tie-breaking)

In Amsterdam, the school choice debates have been resolved for now. Next year, there will be a deferred acceptance algorithm with single tie-breaking, which replaces deferred acceptance with multiple tie breaking. The reason is to avoid inefficiencies that could leave students wanting to trade places.
 Hessel Oosterbeek forwards the following press release:

Nu toch matching voor toewijzing van scholen aan nieuwe brugklassers
Osvo herziet besluit plaatsingsprocedure en volgt Amsterdamse gemeenteraad in wens tot matching
Datum: 27 november 2015


Google translate renders it into English like this:

Now surely matching for allocation of new schools graders
Osvo revises decision placement procedure and following Amsterdam city council in desire to matching
Date: November 27, 2015

The Amsterdam secondary schools united in Osvo match yet again to bring out high school students in a school of choice. In matching children fill a preferred list of several schools, and the computer most favorable and fairest possible distribution calculates. Last year was also matched, but according to a different algorithm. With the currently chosen variant will be more students in the school of their first choice, but there will be more children who are considerably lower on their preferred list. In any case, there is not the problem afterwards between students can be exchanged for a better result.

Osvo still goes first consult with the alderman of education Simone Kukenheim the practical assistance that will get the schools of the municipality for the implementation of the matching. Concrete will be requested from the municipality together with Osvo a central project, the information to parents and children and to take complaints to themselves.

A broad majority in the city council gave to know the alderman of education for this variant of matching. The alderman asked Osvo thereafter published the decision on October 29 to return to draw, to reconsider. With the amended decision in favor of the matching variant Osvo hopes for this year to be able to count on political and social support in the implementation, but also for the results of the placement.

The selected system is also preferred by a large group of parents who made ​​their wish to keep matching known through a petition, in a variant they call matching 2.0. This variant is referred to as DA STB or RSD. DA STB earlier this year in a scientific analysis for the evaluation Osvo compared with DA MTB, which was used in the 2015 matching. DA STB recently came second in the bus in the quest of Osvo to a procurement procedure for 2016. For the pros and cons refer to

Osvo has always its decision to match last year defended by pointing to the starting point of an optimal and fair distribution of the few places in schools where more children enroll than there are places. After a storm of protest about the system, its implementation and information about Osvo selected after extensive review and in consultation with the municipality for a combination of items and match. It would be students in a first-round no preferred list can draw for their school of choice, followed by a relatively small group of about 500 children would be placed on matching the schools still places available. The second round would be conducted according to the system which now is put the whole group of students.
