NCSY (formerly known as the National Conference of Synagogue Youth) is an Orthodox Jewish youth group sponsored by the Orthodox Union. Founded in 1954, it has members in the United States, Canada, Israel, Chile, and formerly also in Ukraine. Its slogan is Inspiring the Jewish Future. NCSY is directly supervised by the Orthodox Union's (OU) Youth Commission chaired by Joseph Stechler of New Jersey.
NCSY is the organizational successor to the National Union of Orthodox Jewish Youth, established in 1942 as an Orthodox youth movement similar to a synagogue men's club or sisterhood. Over time, its emphasis moved to outreach and teaching religious behaviors to adolescents.
Though outreach to public school youth was started by Chabad in the 1930s, the Torah Leadership Seminar, created in 1954 by DCS of Yeshiva University under Dr Abraham Stern, developed the Shabbaton model There was a core of NCSY from two early founded regions Midwest Region (founded 1951) and Southern Region (founded in 1952 by Rabbi Abraham Isaac Rosenberg and Mr. Abe Rabhan of B'nai B'rith Jacob synagogue in Savannah, Georgia). In 1954, Harold and Enid Boxer donated the money to create a national organization from the already-existing Southern and Midwest Regions.
In the 1960s there was an emphasis on NCSY Publications with many volumes written by Pinchas Stopler and then later the Aryeh Kaplan Series.They also put out the NCSY Guide to Blessings and the NCSY Bencher.
During the social upheavals of the 1960s and 1970s, the Orthodox youth of NCSY strove to temper social change through religious tradition. In this period, at least one NCSY chapter took public action on this point, passing a resolution rejecting marijuana and other drugs as a violation of Jewish law. At the 1971 NCSY international convention, delegates passed resolutions in this vein, calling for members to "forge a social revolution with Torah principles."
In the mid-1970s, NCSY started a boys camp at Ner Israel Rabbinical College in Baltimore, MD. It was originally known as "NCSY Goes to Yeshiva," and later changed its name to "Camp NCSY Sports".
In 1970, the Israel Summer Institute for Jewish teens was founded. Rabbi Stolper assisted NCSY in expanding internationally into Canada, Israel, Australia, Chile, and Ukraine.
In 2007, NCSY launched a sexual abstinence campaign.
The organization possesses an International Director within the Orthodox Union, and is subdivided into national, regional and local chapters.
NCSY is divided into geographic regions throughout North America. They are New England, Upper New York, New York-Long Island, New Jersey, Atlantic Seaboard, Central East, Southern, South Florida, Greater Midwest, Southwest, West Coast, Northwest, and Canada. Additionally, NCSY runs programming branches in Israel and now Chile and Germany. Each Region is divided into chapters. A chapter is typically a city, or a group of surrounding towns. In heavily populated Jewish areas like New Jersey, counties may have several chapters.
Many chapters in NCSY appoint or elect a group of NCSYers to serve on a chapter board,who work with the advisors or city directors to assist with programming or outreach. Many regions do the same thing, and have a regional board, who do similar things for the region. The International Board consists of representatives from many different regions.
NCSY's programming is divided into two age groups, "junior" and "senior"; these generally encompass 5th–8th grades and 9th–12th grades, respectively. Some programs span both age groups, but most programming is unique for each.
NCSY's original model was to create the regional Shabbaton, a weekend-long social and educational Shabbat experience based on learning sessions, following in the model of Abraham Stern of Torah Leadership Seminar.
Currently, while on Shabbatons kids are treated to skits, learning sessions and ebbing, where participants sit in a circle around the "circle guy" where they sing songs and do "funny" routines. They are housed either in hotels, camps, or grouped with sponsor families who take them in for the weekend.
NCSY has also begun three amazing new programs called Teen 2 Teen, Call Of Inspiration, and Share A Shabbat.
Teen 2 Teen is program where two teens from different regions sign up to get connected by national NCSY and they pick something to learn. Throughout the year, the teens learn on their own time.
Call Of Inspiration consists of a conference call every Monday at 9pm EST. Ariella Freedman, International president, and Jordyn Kaufman, International Board, host and introduce a different figure in the Jewish community every week. It is always someone with a lot of inspiration to share. Some examples are Charlie Harary of Aish.com and Hart Levine, founder of the Heart To Heart program. People can call in (they are muted) and listen to the person speak for 15 minutes. If you are not available at that time, the call is recorded so anyone can listen to it later.
Share A Shabbat is for kids who normally do not get the full shabbat experience. Kids with Shomer Shabbos homes are encouraged to open up their house for one meal and "Share A Shabbat."

Baruch Lanner is a former director of NCSY convicted for sexual misconduct with minors whom he had contact with through the organization. The investigation began on July 12, 2000, he was indicted in March of that same year and surrendered to authorities and entered a plea of "not-guilty" on April 20, 2000. Lanner was convicted on one account of fondling a student on June 27 of 2002.
Baruch Lanner was hired by NCSY's founder Pinchas Stolper  in 1970 , and remained his superior until 1994. Lanner was already threatened with suspension for sexual contact with two teenage girls in 1972. 
At the time, in 2000 one journalist, Gary Rosenblatt of The Jewish Week argued that the Orthodox community had failed to deal with Lanner properly, and argued that NCSY workers often put the ends above means, sometimes with insufficient regard to the family dynamic or the alienation of teens from their parents. It also sometimes tends to a charismatic quality.
In response the Orthodox Union set up a special commission of investigation. A 54-page public report summarizing a much longer document of investigation, found the following.
The report cited "profound errors of judgment" in the way OU leaders dealt with Lanner and also noted a larger problem of "poor management practices" in the OU, including a lack of accountability by professionals to volunteer leadership, lack of involvement by lay leaders in matters of governance, lack of financial controls and a "total absence of any policies regarding basic ethical issues" in both the OU and NCSY.
As a result of the Lanner scandal, NCSY conducted a thoroughgoing internal review and reformed its structures and running. It created conduct standards, and published a manual on behavior. NCSY has also established an ombudsman hotline.
In October 2011, NCSY was sued by a former advisor and employee for violation of the US Fair Labor Standards Act. The lawsuit claims that she had to work much longer hours than the allowed 40-hour work week.
