(CNN) The board of Florida's largest school district has rejected new sexual education textbooks that it approved three months ago.
The 5-4 vote by the Miami-Dade County School Board on Wednesday leaves students without a sex ed curriculum.
The textbooks cover pregnancy prevention, understanding sexuality and sexually transmitted infections, drugs and alcohol, and relationships, according to descriptions in the book.
In April, the board approved middle school and high school versions of the Comprehensive Health Skills textbook.
District Superintendent José Dotres appointed a hearing officer who recommended the board deny the petitions and adopt the textbooks.
Gina Vinueza, a mental health professional and mother of two in the county, spoke in favor the textbooks at Wednesday's hearing.
Steve Gallon III, vice chair and member of the District 1 School Board in Miami-Dade, took notes as the people voiced their opinions at Wednesday's meeting. »
