The signing of the Paris Peace Agreement on 23rd October 1991 opened the doors of Cambodia to the world after years of internal turmoil. Opportunities for spreading the Gospel abounded and many congregations were formed or regrouped from remnants of the pre-1975 faithful.

To meet the growing pastoral needs of the Church in Cambodia, Phnom Penh Bible School was founded by the late Daniel Yee-Wah Lam with support from many Cambodian believers and Christian organisations. After negotiation with the Cambodian government, PPBS was officially recognized by the government on 16th March 1992.

PPBS now offers a two year Associate Degree in Christian Ministry (ADCM), and a four year Bachelor in Christian Ministry (BCM) and Bachelor of Theology (BTh). PPBS also offers a Master of Arts in Christian Ministry (MACM). Today there are hundreds PPBS graduates who are serving God around Cambodia.

PPBS is faithfully supported by many churches and Christians from numerous countries. Its main supporting organisation is Country Network (CN), a non profit, non-denominational organisation that was begun by Daniel Lam.
