It is. Calvinists most commonly associate with Covenant Theology. Dispensationalism proved a little too biblical - didn't fit the rest of their theology.The first and most noticeable difference is the interpretation of Scripture.
Dispensationalism follows a literal interpretation until it becomes obvious it's not literal. That's a thorn in the rear of the Calvinists.
Covenant Theology starts out in a similar way but has a twist of spiritualizing the covenants of works, grace, and redemption in the prophesies of Israel and the Church.
