Abstract Predictions of the recently developed paleoclassical transport model are compared with data from many toroidal plasma experiments: electron heat diffusivity in DIII-D, C-Mod and NSTX ohmic and near-ohmic plasmas; transport modelling of DIII-D ohmic-level discharges and of the RTP ECH 'stair-step' experiments with electron internal transport barriers (eITBs) at low order rational surfaces; investigation of a strong eITB in JT-60U; H-mode T e edge pedestal properties in DIII-D; and electron heat diffusivities in non-tokamak experiments (NSTX/ST, MST/RFP, SSPX/spheromak). The radial electron heat transport predicted by the paleoclassical model is found to be in reasonable agreement with a wide variety of ohmic-level experimental results and to set the lower limit (within a factor 2 in tokamaks) on the radial electron heat transport in most resistive, current-carrying toroidal plasmas-for T e T crit e B 2/3ā1/2 keV where it is expected to be dominant over fluctuation-induced anomalous transport that scales with a gyro-Bohm diffusion coefficient
