1. A computer-implemented method comprising a plurality of software operations, each software operation being performed using at least one network-connected computer-based system, the method determining a user's risk of dyslexia and comprising: identifying, based on an input received from an input device of the computer-based system, an age category associated with the user; rendering, on a display screen of the computer-based system, a plurality of query pages, each query page being generated from data received by the computer-based system from a remote server over a data communications channel and stored in a memory device of the computer-based system, and each query page comprising a plurality of non-verbal answers that are determined based on the identified age category and are selectable by the user; rendering, via a speaker of the computer-based system, a plurality of auditory queries, each auditory query being rendered as audible sounds and generated from a sound data file corresponding to a non-verbal query, each auditory query being associated with one or more of the plurality of query pages; identifying, via the input device of the computer-based system, a plurality of electronic input selections from the user, each electronic input selection identifying a non-verbal answer from a query page; identifying, via a timer of the computer-based system, timing data associated with the plurality of electronic input selections, the timing data indicating time intervals between the rendering of each of the plurality of auditory queries and the detection of electronic input selections from the user corresponding to each of the auditory queries; assigning weighted scores to each of the electronic input selections from the user, the weighted scores being determined based on the identified age category and the time intervals, wherein time intervals above a first threshold receive a first weighting factor and time intervals below the first threshold receive a second weighting factor; and rendering, on the display screen of the computer-based system, an assessment in a graphical user interface, the assessment identifying a risk of dyslexia for the user based on whether the weighted scores exceed a predefined threshold associated with the plurality of query pages.
