The Toffees sit fourth on the Premier League table but Moyes suggests that could be even higher if it wasn't for the match officials getting a lot of decisions wrong which have cost his team.
"Being a referee nowadays comes with a much higher profile and it is also a much more challenging job," Moyes told reporters.
"The cameras and the technology now allow us to analyse every decision and for anyone who has never refereed a game I can tell you that it is very difficult as I do it most days in training.
"However, here comes a 'but' from me. What we've had in recent games, starting at Reading a few weeks ago, are decisions that have cost us points.
"I will always be the first person to look at the players to finish better or to defend better and not rely on decisions, but as you can see on a regular basis at the moment decisions are affecting the outcome of the games."
