Average Neuropsychology Testing Assistant Salary in Tonga for 2026

How much does a neuropsychology testing assistant make in Tonga?

A typical neuropsychology testing assistant working in Tonga brings home around 1,235 TOP a month before tax. Entry-level pay starts near 7,040 TOP, and the top of the ladder reaches roughly 23,360 TOP for the most experienced and specialised people in the role.

The wide gap between low end and top end reflects how much pay can vary inside the same job title.

How neuropsychology testing assistant pay ranges in Tonga

A good way to think about salary in Tonga is to look at the distribution rather than the headline average. Half of all neuropsychology testing assistants in Tonga earn less than 15,380 TOP a year, and the other half earn more. That middle number is the median, and it is usually more useful than the average for answering "is my pay normal here".

Looking at the quartiles fills in the picture. A quarter of earners take home less than 10,220 TOP (the 25th percentile), and a quarter clear 23,380 TOP (the 75th percentile). The middle 50% of neuropsychology testing assistants sit somewhere inside that band, which is where the typical reader of this page probably lives.

The very lowest reported salaries sit around 7,040 TOP. The highest stretch to 23,360 TOP, though only a small fraction of earners ever reach that level. If you are deciding whether your own offer or current pay is reasonable, work out which of those four bands you would fall into and use that as your reference point.

Neuropsychology testing assistant pay by experience in Tonga

Years of experience is the single biggest lever on pay for a neuropsychology testing assistant in Tonga, ahead of education and almost any other single factor. The longer you have been in the role, the more your employer can trust you to handle complexity, mentor others and act independently, all of which command higher pay. The chart below shows how the typical neuropsychology testing assistant salary changes as you move through the career ladder.

The single largest jump on the ladder is from 0 - 2 Years to 2 - 5 Years, where pay rises by about 51%. That is the point at which a neuropsychology testing assistant typically goes from "competent in the role" to "the person other people in the team learn from", and the market pays well for that step.

Neuropsychology testing assistant pay by education in Tonga

Education sits alongside experience as one of the biggest factors driving neuropsychology testing assistant pay in Tonga. Higher qualifications consistently pull higher salaries, but the size of the gap tends to be smallest at junior levels and widens as people move up. Two people in the same role with the same years of experience but different degrees can end up earning very different money once they reach mid-career.

Neuropsychology testing assistant gender pay gap in Tonga

The gender pay gap is a stubborn feature of almost every labour market, and Tonga is no exception. Male neuropsychology testing assistants in Tonga earn an average of 16,720 TOP a year, while female neuropsychology testing assistants earn around 15,880 TOP. That works out to a 5% gap in favour of men, even when comparing people doing the same work.

A pay gap of this size has a real long-term cost. Over a typical thirty-year career it can add up to several years of pay, and it compounds through pensions, retirement contributions and bonus-linked stock. Some of the gap is explained by women being more likely to work part-time, take career breaks, or be steered toward lower-paying specialisations. Some of it is straightforward unequal pay for the same job, which is harder to defend.

Across all jobs in Tonga, the national average raise is around 5% every 28 months.
