High-spin states in $^{132}\mathrm{Te}$, an isotope with two proton particles and two neutron holes outside of the $^{132}\mathrm{Sn}$ doubly magic core, have been extended up to an excitation energy of 6.17 MeV. The prompt-delayed coincidence technique has been used to correlate states above the ${T}_{1/2}=3.70(9)\phantom{\rule{4pt}{0ex}}\ensuremath{\mu}\text{s}$ isomer in $^{132}\mathrm{Te}$ to the lower states using $^{232}\mathrm{Th}(^{7}\mathrm{Li},f)$ at 5.4 MeV/u and the Indian National Gamma Array (INGA). With $^{9}\mathrm{Be}(^{238}\mathrm{U},f)$ at 6.2 MeV/u and EXOGAM $\ensuremath{\gamma}$-array coupled with the VAMOS++ spectrometer, the level scheme was extended to higher excitation energies. The high-spin positive-parity states, above ${J}^{\ensuremath{\pi}}={10}^{+}$, in $^{132}\mathrm{Te}$ are expected to arise from the alignment of the particles in the high-$j$ orbitals lying close to the Fermi surface, the $\ensuremath{\pi}{g}_{7/2}^{2}$, and the $\ensuremath{\nu}{h}_{11/2}^{\ensuremath{-}2}$ configurations. The experimental level scheme has been compared with the large scale shell model calculations. A reduction in the $p\text{\ensuremath{-}}n$ interaction strength resulted in an improved agreement with the measurements up to the spin of $15\ensuremath{\hbar}$. In contrast, the comparison of the differences between the experiment and these calculations for the $N=76,78$ isotones of Te and Sn shows the increasing disagreement as a function of spin, where the magnitude is larger in Te than in Sn. This behavior could possibly be attributed to the deficiencies in the $p\text{\ensuremath{-}}n$ correlations, in addition to the $n\text{\ensuremath{-}}n$ correlations in Sn.
