David Martinez was the night school Spanish teacher who taught the class Will took in The Spanish Teacher, the twelfth episode of Season Three.
He is described as "the hottest Spanish teacher in Ohio history." He was offered a Spanish teaching position at McKinley when Will decided that he was not fit for Spanish, and only fit for the Glee Club.
He is portrayed by actor and singer, Ricky Martin.
David comes in as a Spanish tutor who teaches night classes, which Will takes to improve his Spanish. His impressive Spanish techniques and charisma catches the eye of Will who invites him to a cup of coffee, which he accepts. After speaking to Will he reveals he used to be a tooth model and that he enjoys singing and wishes he could set up a night school glee club.
He reveals that he is from Ohio, despite his impressive Spanish, but has grown up from Chilean parents who grew up speaking Spanish. His main intention is to teach kids rather than his old job working as a tooth model. He is then invited by Will to the Glee Club to "spice up" the Spanish assignment for the week. He, along with the New Directions, performs a partly Spanish rendition of Sexy and I Know It.
David has later been offered a job as a Spanish teacher at McKinley High for which he is overjoyed and hugs Will in gratitude after Will steps down from the position, admitting his mediocrity in Spanish.
