Unless the Baltimore County Board of Education reverses itself, as of the 2015-16 school year, siblings of elementary magnet school children will not be automatically admitted to the school with their older brother or sister.
The revised rule (as of Apr. 7) states that "kindergarten priority placements will no longer be granted beginning with the 2015-2016 school year" (see Article VI.A.1).
This means, if you have a child at a magnet school and your younger child is not admitted via random lottery, you will be forced to either take your older child out of the school they've attended in previous years or send your elementary age children to two separate schools.
Information regarding consideration of the repeal should have been disseminated, prior to the decision, to all school communities potentially affected by it. This situation is another example of the school system making important policy changes without ensuring that proper communication, consideration of various perspectives, and deliberation have occurred.
