Precise estimates of the nucleon charges $g_A$, $g_S$ and $g_T$ are needed inmany phenomenological analyses of SM and BSM physics. In this talk, we presentresults from two sets of calculations using clover fermions on 9 ensembles of2+1+1-flavor HISQ and 4 ensembles of 2+1-flavor clover lattices. We show thathigh statistics can be obtained cost-effectively using the truncated solvermethod with bias correction and the coherent source sequential propagatortechnique. By performing simulations at 4--5 values of the source-sinkseparation $t_{\rm sep}$, we demonstrate control over excited-statecontamination using 2- and 3-state fits. Using the high-precision 2+1+1-flavordata, we perform a simultaneous fit in $a$, $M_\pi$ and $M_\pi L$ to obtain ourfinal results for the charges.
