16 Days in Afghanistan
16 Days in Afghanistan is a 2007 documentary about the journey of Afghan-American Anwar Hajher (director) traveling to his homeland Afghanistan after 25 years to rediscover his country.
 The film is produced by Mithaq Kazimi and is the first documentary since the fall of Taliban to be shot in those provinces which remain under the heavy influence of the Taliban.
 It is also the first professionally produced documentary about Afghanistan by a team of Afghan filmmakers and has become a reference film used by many, including Penguin Books's study guides about Afghan-related books.
High School (1968 film)
High School is a 1968 American documentary film directed by Frederick Wiseman that shows a typical day for a group of students at Northeast High School in Philadelphia, Pennsylvania.
 It was one of the first direct cinema (or cinéma vérité) documentaries.
 It was shot over five weeks in March and April 1968.
 The film was not shown in Philadelphia at the time of its release, due to Wiseman's concerns over what he called "vague talk" of a lawsuit.
Polly Plumer
Polly Anne Plumer was the National High School record holder in the Mile run at 4:35.24, set in open competition at UCLA May 16, 1982 while a student at University High School (Irvine, California).
 That distance is no longer run in high school competition since the NFHS converted to metric distances in 1980, but it is still an international record event.
 Her record lasted over 30 years until it was surpassed on January 26, 2013 by Mary Cain, indoors, running 4:32.78 at the New Balance Games.
 Cain later improved her own mark to 4:28.25, also indoors at the Millrose Games.
 Because Cain's marks were set on an indoor track, which is generally considered to be more difficult, they were not recognized by "Track and Field News" the ratifier of high school records in non-NFHS sanctioned events (high school athletes in open competition), so Plumer retains the record as published.
 Christine Babcock, born 8 years and 3 days after Plummer's record, running for Woodbridge High School, also in Irvine, took the record in the more commonly run but shorter 1600 meters to an equitable 4:33.82 in 2008.
 Babcock's record was improved to 4:33.29 in 2014 by Alexa Efraimson. La Vista High School

The Katie Sierra suspension controversy began in October 2001 when high school student Katie Sierra was suspended from Sissonville High School for her activism in opposition to the bombing of Afghanistan.
 The fifteen-year-old Sierra was engaged in anti-war activism at her school, near Charleston, West Virginia, wearing clothes with handwritten messages objecting to U.S. militarism, racism, sexism, and homophobia.
 She applied for permission to start an anarchist club at the school, and was denied by the school's principal.
 Her attempts at publicizing the club led to her being suspended from school for three days.
 Incendiary comments by the principal and the members of the school board were reported in the press and provoked a controversy that garnered national and international media attention. Alexander M. Patch American High School
Alexander M. Patch American High School (also known as "Patch American High School" or "Patch High School") was an English language high school on Patch Barracks in Stuttgart, Germany operated by DODEA (formerly known as DoDDS).
 Opened in 1979; the students were largely military dependents whose sponsors were assigned to units of the Stuttgart Military Community, including Patch Barracks, Robinson Barracks, Panzer Kaserne, and Kelley Barracks.
 The school was named after Alexander McCarrell Patch, a General in the United States Army during World War II.
 From 1979-2006 the school operated for grades 7-12.
 With the 1992 closure of Stuttgart American High School in Pattonville, Patch High School became the only DODEA (DoDDS) High School in the Stuttgart area.
 After 2006 the school changed to 9th-12th due to projected increasing enrollment and middle schools created at nearby Panzer Kaserne and Robinson Barracks to be used by these students.
 Patch High School officially closed June 30, 2015.
 The newly built Stuttgart High School (Germany) on Panzer Kaserne will be the only DoDEA (DoDDS) high school in the Stuttgart area starting with the 2015-16 school year. KDK Factory
