To simplify the expression \( a^{-2} \cdot a^5 \cdot a^{-3} \), we use the property of exponents that states:

\[
a^m \cdot a^n = a^{m+n}
\]

1. Combine the exponents by adding them:

\[
a^{-2 + 5 - 3} = a^0
\]

2. Since \( a^0 = 1 \) for any non-zero \( a \):

\[
a^0 = 1
\]

So, the simplified expression is \( 1 \).
