How to create small bullets within a subsubsection

Question

I'm trying to figure out how to shrink the bullet points within my subsubsections. Any advice would be greatly appreciated!

\documentclass{article}
\usepackage{titlesec}
\usepackage{titling}
\usepackage[margin=1in]{geometry}
\usepackage{hyperref}
...
\titleformat{\section}
{\Large\bfseries}
{}
{-.12em}
{}
\titleformat{\subsection}
{\large}
{}
{0em}
{}
\titleformat{\subsubsection}[runin]
{\large}
{\hspace*{.25in}$\bullet$}
{.5em}
{}
\titlespacing{\subsubsection}
{0em}{-.25em}{0em}
\titlespacing{\subsection}
{0em}{.25em}{0em}
\setlength\parindent{25pt}
\begin{document}
...
\section{\vspace{-.7em} Education}
\subsection{{\vspace{-.25em} school} \hfill \normalsize location}
\subsubsection{B.S. Candidate \hfill \normalsize May 2023} \subsubsection{Relevant Coursework: previous courses currently \vspace*{-.25em} \linebreak \phantom{1em} : current courses} \subsubsection{GPA}
...
\thispagestyle{empty}
\end{document}

Welcome to TeX.SE...

Try with the below:

%%Small bullet
\newcommand{\smallbullet}{} % for safety
\DeclareRobustCommand\smallbullet{%
  \mathord{\mathpalette\smallbullet@{0.75}}%
}
\newcommand{\smallbullet@}[2]{%
  \vcenter{\hbox{\scalebox{#2}{$\m@th#1\bullet$}}}%
}

Then use \smallbullet instead of \bullet

Actually, this was suggested by some one else, but I missed the URL link...
