The Spanish Teacher

"The Spanish Teacher" is the twelfth episode of the third season of the American musical television series Glee, and the fifty-sixth overall. Written by co-creator Ian Brennan and directed by Paris Barclay, the episode aired on Fox in the United States on February 7, 2012. It features special guest star Ricky Martin as a night-school Spanish teacher whom Will Schuester (Matthew Morrison) introduces to McKinley High, and shows several of McKinley's teachers competing for a promotion when a tenured position unexpectedly becomes available.

The episode received mixed to positive reviews, and many critics considered Martin to be a highlight. Reaction to the music as a whole was less enthusiastic than for the episode itself, though "La Isla Bonita" and "Don't Wanna Lose You" were given a generally favorable reception. The former song charted on both the Billboard Hot 100 and the Billboard Canadian Hot 100; of the remaining four singles, "Sexy and I Know It" debuted on the Billboard Hot 100, and the other three singles did not chart.

Upon its initial airing, this episode was viewed by 7.81 million American viewers and received a 3.3/9 Nielsen rating/share in the 18–49 demographic. The total viewership was down significantly from the special tribute episode, "Michael", which aired the previous week.
