Katok Monastery's third abbot, Jampa Bum (1179-1252), whose 26-year tenure as abbot ended in 1252, "is said to have ordained thousands of monks from across Tibet, and especially from Kham region of Minyak (mi nyag), Jang ('byang), and Gyarong (rgyal mo rong)."
The original gompa fell into disrepair and was rebuilt on the same site in 1656 through the impetus of Tertön Düddul Dorje (1615–72) and the terton Rigdzin Longsal Nyingpo (1625-1682/92 or 1685–1752).
Katok Monastery held a reputation of fine scholarship. It is held that prior to the annexation of Tibet by the Chinese in 1951, that Katok Monastery housed about 800 monks.
According to The Tibetan Buddhist Resource Centre, disciples of Kenpo Munsel  and Kenpo Jamyang at Katok Monastery in 1999 compiled a Katok edition of the Kama (Wylie: bka' ma shin tu rgyas pa (kaH thog)) in 120 volumes: "... twice the size of the Dudjom edition, it contains many rare Nyingma treatises on Mahayoga, Anuyoga, and Atiyoga that heretofore had never been seen outside of Tibet."
According to Alexander Berzin,
Katog has 112 branch monasteries, not only in Tibet, but also in Mongolia, Inner China, Yunnan, and Sikkim. For instance, Katog Rigdzin-tsewang-norbu (Ka:-thog Rigs-‘dzin Tshe-dbang nor-bu) (1698-1755) founded a large branch in Sikkim, and when the Eighth Tai Situ Rinpoche, Situ Panchen Chokyi-jungney (Si-tu Pan-chen Chos-kyi ‘byung-gnas) (1700-1744), visited China, he stayed at the Katog branch-monastery at the Five-Peaked Mountain of Manjushri (Ri-bo rtse-lnga, Chin: Wutai Shan), to the southwest of Beijing.
Kathog Monastery became a bastion of the Anuyoga tradition when it became neglected by other Nyingmapa institutions. The Compendium of the Intentions Sūtra (Wylie: dgongs pa ’dus pa’i mdo) the root text of the Anuyoga tradition was instrumental in the early Kathog educational system. Nubchen Sangye Yeshe wrote a lengthy commentary on the Compendium of the Intentions Sūtra rendered in English as Armor Against Darkness (Wylie: mun pa’i go cha).
