Apparently, Binet wasn't the first person to make an IQ test. And PISA etc. weren't the first to try to standardize educational testing across countries. http://emilkirkegaard.dk/en/?p=7783

The NY Regents Examinations date back to 1866 and were standardized. Standardized Chinese civil service exams are far older. I tell my students that Binet's test was the standardized test with scientifically-derived content. That's the key breakthrough.
Is Binet approach really that much more scientific? Seems like he relying a lot of trial and error in inclusion of items for the younger ages. Point to nose? At least Piaget had a more elaborate system.

Trial and error was what made it scientific ;) Piaget was Binet's assistant BTW and his theory was inspired by the age patterns he saw in the tests he marked
-
I know Piaget was Simon's assistant, but I don't think he worked for Binet. Paget was 15 when Binet died, and at that time he was a precocious teenager writing about mollusks. Was he even studying psychology then?
-
So, he graded tests, but it doesn't say he helped revise the Binet scales.
-
Yeah, basically.
-
All this being said, Binet's breakthrough was important, but given the precursors (Galton, standardized educational tests, Thorndike, etc.), I think that a scientifically derived test was inevitable in the early 20th century. Binet just got there first.

Binet had been studying child cognition since 1890. With that knowledge and his theory of age-driven cognitive development as his foundation, yes, it was more scientific. By today's standards, Binet's methods were primitive, but in 1904-1905, they were advanced. 1/2

You're right that Binet used trial and error, but that item evaluation process (where he threw out items that didn't work and replaced them with new items) was an empirical process. I'm not aware of any earlier test that was created empirically. 2/2
