I think you meant to say "decreasing" unemployment.
According to FactCheck.org and PolitiFact.com: Since 2009, U.S. has created more jobs than 'every other advanced economy combined'
When he got into office unemployment was at 10% and today it's around 5.7%. In September 2014 Forbes Magazine had a article stating The Bureau of Labor Statistics: Jobless claims were just over 300,000; lowest since 2007. It's been reported over 4 million jobs have been added.
However it's not about the "numbers" but rather the types of jobs that concern most Americans. We're not seeing as much middle class and higher wage jobs being created as we want to see.
Therefore if the question is strictly based on the number of jobs added during his terms the answer is "yes" he's done a good job.
Nevertheless if one analyzes the (wages) of the average job created it's less than the previous job that was lost during "The Great Recession" under George W. Bush.
