As a non-eu/eec citizen with a valid work permit in Malta, under EU law you are entitled to apply for the family reunification visa for your wife.
In order to do this, then you must already be living in Malta before you apply for a visa for her.
You must meet the requirements set out under Maltese law which includes providing evidence of your marital status, being over 21, already living and working in Malta with a valid work and residence permit valid for at least 1 year, earning at least average salary + 20% for every family member wishing to join, having accommodation which is suitable for your family, sickness insurance.
You then apply, pay the fees, and a decision is made. Your wife is then issued a visa and can travel to Malta to join you where she will be able to live and work there, and have access to education to the same level as you can.
There are no details upon the average processing times, but the law states that it must not take longer than 9 months to make a decision! If I was you, I would plan on it taking 3 - 6 months.
