The Graduate Reasoning Test Battery (GRT1) is intended for selection of persons for specialised positions that are particularly intellectually demanding, and with a strong reliance on numerical ability. Similarly to the GRT2, the GRT1 assesses Verbal, Numerical and Abstract Reasoning, but at a considerably higher level of difficulty. The GRT1 subtests can be administered separately or together as a battery. Administration is available using pencil-and-paper, in-person online, or via a generated link under remote supervision.
