Mission Statement

Mercy High School, a Catholic college preparatory school immersed in the tradition of the Sisters of Mercy, educates and inspires young women of diverse backgrounds to lead and serve with compassion.

Vision Statement

A Mercy High School education is rooted in the Catholic faith and the charism of the Sisters of Mercy.  Our school welcomes and nurtures diverse young women, following the example of Venerable Catherine McAuley, Founder of the Sisters.  In order to engender life-long discovery, Mercy High School strives to exemplify an innovative learning community with committed educators and engaged students who seek and share knowledge and wisdom.  Our students, graduates, and other members of this Mercy family aspire to live out their relationship with God as they:

  • recognize their own unique gifts and talents, and appreciate those of others.
  • seek personal, academic and professional excellence.
  • give voice to and exemplify their ideals.
  • pursue compassionate justice through action.

Our cherished community is sustained and advanced by the active support of all members and friends.


The Sisters of Mercy, West-Midwest Community, sponsors of Mercy High School, identify the following five values as characterizing their ministries: Human Dignity; Mercy; Justice; Service; Option for the Poor. These values inspire and challenge all at Mercy High School in the daily living of our spirit.

My God, I am yours for time and eternity. Teach me to cast myself entirely into the arms of your loving providence, with the most lively, unlimited confidence in your compassionate, tender pity. Grant me, O most merciful Redeemer, that whatever you ordain or permit may be acceptable to me. Take from my heart all painful anxiety; suffer nothing to sadden me but sin, nothing to delight me but the hope of coming to the possession of you, my God and my all, in your everlasting kingdom.
