Janison Education Group (ASX:JAN) said the New Zealand Ministry of Education has selected it as the preferred provider for new assessment and aromatawai tool for schools nationally with an initial three-month contract valued at AU$750,000, according to a Tuesday Australian bourse filing.

Under the contract, the company will provide a long-term, accessible, and scalable technology to support the Ministry in assessing students from Years 3 to 10 across reading, writing, maths, pānui, tuhituhi, and pāngarau.

The company added that the initial contract value is not material to its earnings, but it has a key deliverable of a five-year master services agreement, which is expected to represent a "substantially larger" commercial opportunity.

The company's shares soared 20% in recent Tuesday trade.
