Three years later, in 2006, City College was ranked 206, and in 2007 it was ranked 258. Given an estimated 27,500 public high schools across the nation, in 2007 ranking placed City College in the top one percent of all high schools. In its criteria, Newsweek divided the number of Advanced Placement and International Baccalaureate tests taken by the number of graduating seniors. The magazine stated that the measure showed schools which were committed to helping students take college-level courses. In addition to the academic resurgence of the school, the building was recognized for its historical and architectural interest. The Castle on the Hill was honored in 2003 by being placed on the National Register of Historic Places. This designation coincided with the 75th anniversary of the structure and campus as well as City College's 165th year of existence. On April 24, 2007 it earned the additional distinction of being listed as a Baltimore City Landmark. Mayor Sheila Dixon stated that: "The castle on the hill, as City College is known, is truly a historic landmark. It is worthy of preservation and acknowledgment." The landmark status bill was passed by the city council in accordance with a recommendation made by the council's staff, which found that the building dates from a historic and architecturally significant period. This new status prevents the building's exterior from being altered without the approval of the city's Commission for Historical and Architectural Preservation. However, the previous year City College was a victim of vandalism at the hands of a group of children ranging in age from 8 to 15, as a renovation of the school neared completion. In the summer of 2007, scenes from the 2008 sequel Step Up 2'', set at the fictional Maryland School for the Arts, were filmed at City College. In 2007 controversy about the academic program arose, when members of the Baltimore City College Alumni Association argued that the IB Program was diverting a significant amount of the school's resources to benefit a fraction of the student population. Approximately 30 students out of 1300 were enrolled in the full IB Diploma Program at City College. Some members also argued that the rigidity of the program did not give students enough flexibility.
