Emmitt Smith, Niece Nash, and Miss USA 2012 Olivia Culpo served as judges in the pageant. They evaluated the 80 Miss Universe 2015 contestants across the globe in the swimsuit, evening gown, and interview competition.

The contestants were narrowed down to ten contestants, after the swimsuit competition. They included Miss USA, Miss Japan, Miss Australia, Miss France, Miss Philippines, Miss Venezuela, Miss Curacao, Miss Dominican Republic, Miss Thailand, and Miss Colombia.

Following the evening gown competition, the contestant pool narrowed down to five - Miss France, Miss USA, Miss Philippines, Miss Australia, and Miss Philippines.

During the question and answer portion, the top five got a question each and had one chance to answer it.

Miss Australia was asked about legalizing Marijuana in Australia. She said that legalization had been proven to be beneficial in helping people in certain circumstances, such as in treating cancer, but the government should weigh up both sides.

When Miss France was asked on how to fight terrorism in line with Paris attacks, she said they had to know where the problems originate and find the problem at its heart.

Miss Colombia was asked for her view on ways to handle drug abuse and she said that education begins at home.

Miss USA almost ran out of time when asked about gun control. According to Miss USA, individuals had the right to protect themselves, but the United States needed stronger regulations.

Miss Philippines was asked if the U.S. should have a military presence in the Philippines. She said that the U.S. and the Philippines had a good relationship with each other. She added that they had been colonized by the Americans and they had their culture. For Miss Philippines, the country was very welcoming with the Americans and she did not see any problem with that at all.

After the question and answer portion, Miss USA, Miss Colombia, and Miss Philippines emerged as the top three. The ladies answered one single question: "Why should you be the next Miss Universe?"

Miss USA was first asked why she would be the next one to be crowned as Miss Universe. She said that she was passionate and driven. For Miss USA, she wanted to believe in themselves and be themselves. She also wanted equality for men and women and to empower women all over the world, according to Las Vegas Sun.

When it was Miss Colombia's turn, she said that she should be the next Miss Universe, since she had all the attributes that a Latin woman and a Colombian woman had, a woman that was full of feeling, and a Miss Universe should have for all of her events.

Miss Philippines was the last one to voice her thoughts on the reason why she should be the next Miss Universe. She said that the title was an honor with responsibilities. She added that she would shine the light on youth and should raise awareness to causes like the spread of HIV. For Miss Philippines, she was confidently beautiful with a heart.
