The Scot stepped up into his first permanent managerial role following spells as a coach when he replaced Roy Hodgson at the west Midlands club in June 2012.
With four games of the season remaining, West Brom have already exceeded their points tally for 2011/12 and look good to improve on last year's finishing position of 10th place in the Premier League.
But Clarke, who coached at Newcastle, Chelsea, West Ham and Liverpool before taking the reins at West Brom, has eyes on a strong finish to the season with his side currently lying in eighth position.
"It's been a pleasing season for me, given it's my first year in the hot seat," Clarke admits.
"We're on 48 points but if it stops now and we get no more points I'll be very, very disappointed.
"That's the kind of person I am. We can get more points from the last four games.
"I said in June I wanted 50 points. The problem is, if we win the next game we're on 51! So we need more goals after that. I want to be successful."
The Baggies have twice climbed as high as third in the table, but following a mid-season dip in form they have recovered enough to leave Clarke with hopes of catching the club that dismissed him alongside manager Kenny Dalglish last summer.
He added: "I don't think anyone can accuse us of coasting - you could see the way they've played, the way they've chased matches, the effort they've shown.
"I'm aiming to finish higher. Whether we can catch Liverpool I don't know but finishing in the top eight is a good achievement."
