Using LEGO to test children's ability to visualize and rotate 3D shapes in space:
Researchers at the University of California San Diego have developed a test that uses children’s ability to assemble LEGO pieces to assess their spatial visualization ability. Spatial visualization is the ability to visualize 3D shapes in one’s mind, which is tied to increased GPAs and graduation rates in STEM college students.
At the college level, a widely used assessment is the Purdue Spatial Visualization Test: Rotations, or PSVT:R, which is a 20-minute timed test consisting of a series of multiple-choice questions that are geared towards students 13 and older. Van Den Einde and Delson wanted to develop an assessment that would be more suitable and engaging for students at lower grade levels. They turned to LEGO, which was designed with that younger age range in mind and is familiar to many children. To pass the test, students have to assemble a set of LEGO pieces into a specific shape, such as a whale or a small plane, while only being given a picture of the final shape but no step-by-step instructions. The time it takes students to build the correct solution is the metric used for assessment.
[...] In order to validate the test, the researchers had students in two freshman engineering graphics courses take both the LEGO assembly test and the PSVT:R. Students took the tests both at the beginning and end of the quarter. During the course, they were trained with the Spatial Viz app. Test results show a statistically significant correlation between outcomes on the LEGO test and the PSVT:R.

The problem with testing for adults it that it's far more likely that adults have developed other ways of solving problems that are not related to the skill or ability that the test intends to test. There's also a much wider range of abilities as adults than there is for kids. It's one of the reasons why IQ tests are even less commonly given to adults as it's much, much harder to test the innate abilities of adults due to life history and uneven access to education.
There's also far less utility as adults are largely on some sort of a trajectory in life, one that's much harder to change than it is in kids. Whereas kids being encouraged to look at careers that better suit their abilities and interests can be helpful, doing so with adults is much more expensive and time-consuming.
