The Royals secured their play-off place with a 1-0 win over Wigan on Saturday and are third with a game left to play.
"For us, it's important to stay up there and be happy with where we are going into the semi-final," Stam said.
"It's going to hard and a big battle as all the teams up there are good and have quality individuals."
Stam, who took charge of Reading in the summer, praised the squad's achievement in finishing in the top six.
"I'm very proud of the players," he told BBC Radio Berkshire. "A top six finish is something you hope for at the beginning of the season, but that depends on the progress of the team.
"It's a big achievement and a big compliment to the squad in how they've done this season."
Reading travel to Burton for their final game of the regular season on Sunday and would face sixth-placed Fulham in their play-off semi-final as things stand.
But, former Manchester United defender Stam is not too concerned with who they might face.
"We're going to give it our best shot," he said. "We want to finish the final game well as we don't want to go into the play-offs with a disappointment."

Two explosions near the finishing line killed three people and injured at least 140 about two hours after the winners had completed the race.
"If this had happened two hours earlier, maybe I would have been among the victims," Mr Korir said.
He had been celebrating Kenyan Rita Jeptoo's victory in the women's race.
"The joy that we had has all been taken away," Mr Korir told the BBC's Newsday programme.
Ms Jeptoo comes from the Cherangany constituency, for which Mr Korir was elected an MP in last month's election.
Despite the blasts and his political career, he says he will continue to compete in marathons - even in Boston, if it is held again next year.
"My attitude to marathons will never change but my attitude to life may change," he said.

He said it was "scary" when he heard the news of the blasts.
He said on hearing the news, he immediately checked on his parents-in-law, who were visiting, along with his coach.
Kenya's ambassador to the US has told the BBC that none of the eight Kenyan athletes running the marathon were wounded in the blasts.
Two South Africans were treated in hospital for minor injuries but have now been released, officials say.
The men's race was won by Ethiopia's Lelisa Desisa, ahead of Kenya's Micah Kogo.
The annual Boston Marathon this year had a field of about 23,000 runners and was watched by hundreds of thousands of spectators.
It is held on Patriots' Day, a Massachusetts state holiday which commemorates the first battles of the American Revolution in 1775.
UK police are reviewing security plans for Sunday's London Marathon, the next major international marathon, following events in Boston.

Brig Gen Tlas, said to be in his mid-40s, is a member of Syria's most powerful Sunni family, which has given its support to the Assad's Alawite clan for decades.
The general's father, Mustafa Tlas, was Syria's longest serving defence minister, who helped to ensure Mr Assad's succession to the presidency in 2000 following the death of his father.
As a young man, Gen Tlas also attended military training with President Assad.
So, naturally, he was a member of Mr Assad's so-called inner circle, serving as commander of an elite Republican Guard unit.
The general - together with his wife - was also seen as a leading figure on the Damascus social scene, entertaining foreign envoys, artists and the media.
But sources say he has become increasingly frustrated in recent months over the violent crackdown by the security forces on protesters.
He was reportedly under a form of home arrest since May 2011, following his meeting with the opposition to try to start a political dialogue and also because of his opposition to the clampdown.
The current regime, he once reportedly said, was taking the country to hell.
Most of Syria's leaders are Alawite, but Gen Tlas is a Sunni Muslim, and his desertion may encourage other Sunni officers to consider their allegiances.
Reading manager Jaap Stam believes momentum rather than a highest-placed finish will be most important going into the Championship play-offs.
