The Villans narrowly avoided relegation from the Premier League during the last campaign thanks to a strong finish.
However, Clark believes that the players at Villa Park have learned from their struggles last time out.
"We are a year older and hopefully we are still improving," he told the Express & Star.
"We are learning from some of the mistakes last season. We are a young side and we've had a tough start this season but I think we are progressing and moving forward."
Clark is currently on international duty with the Republic of Ireland ahead of their World Cup qualifiers against Germany and Kazakhstan.
