I would. Most modern systems of education have their roots in 1748, and either are derived from or inspired by reforms to the Prussian educational system to guarantee free and compulsory elementary school education between the ages of 5 and 14 as taught by secular professional teachers for the full populace.
If you mean the university and college levels, they have interesting differences from the 18th century, but are recognizably similar in regards to basically everything besides cost and curriculum differences we'd expect due to changes in societal needs, technical advancements, and changing interests.
I wouldn’t date the current system prior to one-room schoolhouses becoming uncommon. That’s an enormous change.
If we’re going back farther than that, then I’m really having a hard time seeing where the stagnation comes in—I don’t agree with that even past that point (gifted education alone is only just now starting to develop into something halfway useful, and that’s a very recent change in just one small part of primary and secondary education) but if we’re going farther back, then… what?
