An increasing number of Hamilton's high school teachers are making more than $100,000, according to this year's sunshine list.

The list, released annually, is an Ontario government disclosure of public-sector salaries. It provides the salary details for anyone on the provincial payroll earning $100,000 or more.

Thirty-four high school teachers in the public board and 54 in the Catholic board made six figures in 2012, according to the sunshine list released Thursday afternoon.

Many of the teachers are department heads, which means an additional $5,471 allowance for overseeing their departments, said Patrick Daly, chair of the Hamilton-Wentworth Catholic District School Board. This is in addition to the maximum $94,622-per-year salary for a teacher at the top of the grid.

"In our board, our high schools are very large," Daly said. "In some departments, such as English and religion and math, you have a number of teachers."

Department head duties include managing the curriculum within those departments, overseeing programs and supporting principals, Daly said.

In the Hamilton-Wentworth District School Board, teachers making six figures likely do extra work teaching continuing education classes nights or over the summer, said associate director Ken Bain.

"The answer is really within the area of community and continuing education."

Last year's list shows 21 teachers making six figures in the public board in 2011. All but one are identified only as "teachers" without specifying high school or elementary.

There are no Catholic board teachers on last year's list.

In 2012, 260 employees of the Hamilton-Wentworth District School Board earned more than $100,000. In 2011, there were 224.

Director John Malloy topped the public board list at $231,980.74 plus $11,236.51 in benefits. Malloy was the only staff member to crack the $200,000 mark. In 2011, Malloy earned $220,980.80 and $10,816.58 in taxable benefits.

One hundred seventy-three employees of the Hamilton-Wentworth Catholic District School Board earned six figures compared to 104 the year before.

Director Patricia Amos earned $214,000.96 and $3,346.11 in benefits, the highest in the board. That's up from $208,558.98 the year before.

Teacher salary grids are determined through negotiations between provincial unions and the province. The maximum salary is the same at every school board, Daly said.

The increasing number of staff on the sunshine list shows why the province should increase the minimum limit for the disclosure list, he said.

"I understand the need for transparency and the public's right to know, but I strongly suggest that the government increase the $100,000," he said.

"(The list) was clearly for the public to be aware of what peope on the high end were making. I don't think it was ever intended to list hundreds of thousands of names."
