Natalia Valentin and Florida International are 14-0 in Sun Belt Conference play

With only three and a half weeks left before the NCAA Championship field is announced (Sunday, Nov. 29 at 3 p.m. ET on ESPN News), it's time to examine how some of the big conference races are shaping up. First we'll take a quick look at what's happening at the top of the standings in each of the 13 leagues that have at least one team that is ranked or receiving votes in this week's AVCA poll. Below that, we revisit the 19 squads across the country that continue to remain perfect in conference action.

Atlantic 10
Dayton leads the way with an 11-1 league mark, with four matches to go. No. 21 Saint Louis stands one-half game back, at 10-1, with five to play - though the Flyers topped the Billikens in the teams' only meeting of the regular season. The conference tournament - which has been won by one of those two schools for each of the last six years (Dayton in 2003, '04, '05 and '07; Saint Louis in 2006 and '08) - takes place Nov. 20-22 in Dayton, with six teams qualifying. The championship match (Nov. 22, 4 p.m. ET) will be televised live by CBS College Sports Network.

Atlantic Coast
No. 16 Florida State is atop the standings with a 12-1 conference record, with seven matches remaining. The Seminoles have a one-game lead on Duke (11-2), and those two will meet on Friday in Tallahassee.

UT - seeking its first outright Big 12 title since 1997 after being co-champs in each of the last two years - won in three sets in Austin in September.
