Jackie Alexander joined the ETSU women’s basketball program in April of 2021. She enters her third season in 2023-24.

In just her second season with the program, ETSU enjoyed the largest turnaround in NCAA Division I Women's Basketball. The program went from a 6-22 record in the 2021-22 season to a 25-10 record in 2022-23 for a 19-win improvement. The improvement is the seventh-best turnaround in NCAA women's basketball history. Alexander also aided ETSU in setting new school records for wins in a season (25) and non-conference wins in a season (13), winning the program's first postseason game since 1995 with two wins in the Women's Basketball Invitational, as well as the team's first College Insider Top 25 Mid-Major ranking since 2010. The Bucs were either ranked or receiving votes for 10 straight weeks (Dec. 20, 2022 - Feb. 21, 2023) and were ranked for three of those (Dec. 27, 2022 - Jan. 10, 2023) with Alexander on staff.

Also with Alexander's assistance, ETSU set school records for made three-pointers in a single season (228), best margin of victory (69), fewest points allowed in a game (26), fewest points combined (75) in a 44-31 win over Vanderbilt, as well as the single-game three-pointers made record in a win over SoCon regular season champion Wofford (16).
