The Idaho Department of Labor has approved workforce development training grants for eight companies totaling $4.8 million in the past few months.

The biggest chunk goes to Chobani, ATK, and Central Garden & Pet Supply Co.

New York-based Greek yogurt maker Chobani is building a plant in Twin Falls. It has started training managers and is eligible for reimbursements of up to $3.3 million from the state. The department estimates Chobani will train 583 people, at an average cost of $5,700 per person.

ATK makes ammunition in Lewiston. The company is headquartered in Virginia and has about 650 employees in Idaho. According to the Department of Labor, ATK plans to add 150 people to its payroll. The company can get reimbursed for $436,000 in training costs. The average cost to train an ATK employee is about $2,900.

Central Garden & Pet, based in Walnut Creek, Calif., has been moving some of its back-office operations to Boise. It could have up to 250 professional, salaried positions, officials at the Boise Valley Economic Partnership told the Idaho Statesman in April. The company said the state’s training support was a factor in its decision to come to Boise.

The workforce grants are paid for by a tax on business. To qualify, a company must pay at least $12 an hour and offer health benefits, and most of its goods must be sold outside of the region.
