In this paper we provide predictions for the BH population that would be observable with planned JWST surveys at $5 \le z 15$. We base our study on recently developed Cosmic Archaeology Tool (CAT), which allows us to model seeds formation and growth, while being consistent general of AGNs galaxies observed $4 7$. find will a complementary view active BHs $z > 5$, JADES-Medium/-Deep capable detecting numerous populate faint-end distribution, COSMOS-Web sampling large enough area detect rarest brightest systems, CEERS/PRIMER bridging gap between these two regimes. The relatively small field above preferentially selects masses $6 \leq {\rm Log} (M_{\rm BH}/M_\odot) < 8$ $7 10$, residing in metal poor (${\rm (Z/Z_\odot) \ge -2$) massive ($8\leq (M_*/M_\odot) 10$) galaxies.
