  Over fields of characteristic $2$, Specht modules may decompose and there is
no upper bound for the dimension of their endomorphism algebra. A
classification of the (in)decomposable Specht modules and a closed formula for
the dimension of their endomorphism algebra remain two important open problems
in the area. In this paper, we introduce a novel description of the
endomorphism algebra of the Specht modules and provide infinite families of
Specht modules with one-dimensional endomorphism algebra.
