Livermore, who made his only appearance to date for the England senior side against Italy in a friendly in 2012, has been included in the squad for the upcoming games against Germany and Lithuania.
The midfielder joined West Brom in a reported £10million deal from Hull in January and Pulis believes he deserves his call-up following his performances since his arrival at the Hawthorns, although the Albion boss is convinced the 27-year-old can improve further.
“I am absolutely delighted for him – he’s been a pleasure to have around the club from the moment he signed and thoroughly deserves this selection,” he told the club's official website.
“Jake has so much to offer and is only just really starting with us. There is a lot more to come.
"At the moment, he is still in the process of understanding exactly what we want from him in his role with us but he has all the tools to complete the task.
“It’s brilliant news for the club. I am told Albion haven’t had an outfield player on the pitch for England since Steve Hunt in 1984 and that’s much too long.
"Let’s hope Jake gets his opportunity because he deserves it.”
