To meet these needs, CONEXIONES has initiated a number of programs to provide assistance and support to encourage students to complete high school, to consider higher education opportunities, and to be successful in their career choices. CONEXIONES has been an advocate for changes in the policies, practices, and personnel of the Howard County Public School System, for the purpose of improving the performance and the educational outcomes for Hispanic students. Dr. Murray Simon served as its first president from its inception until 2007. He was suceeded by Felicita Solá-Carter until December 2014.
