House amendment makes the following changes to the 2nd edition:

Directs the State Board of Education to contract with a private, nonprofit corporation to administer the provisions of this act by October 1, 2015 (was, August 1, 2015).  

Requires the nonprofit corporation contracting with the State Board of Education to, by November 1, 2015 (was, October 1, 2015), issue requests for proposals from local boards of education for local initiatives designed to develop advanced teaching role prototypes. Amends the specified criteria that are to be included in submitted letters of intent by the local board of education, including amending the language that provides that a classroom teacher is required to be rated as "highly effective" and how that rating is calculated. Also amends the provisions and standards by which teachers are rated in regards to teachers serving in advanced roles receiving an additional 3% salary. 

Adds language providing that local school administrative units can also use grant funds to provide salary supplements or to implement other elements of their advanced teaching role plans. Amends other provisions concerning the use of funds, deleting language that provided that allocated funds cannot be used by local school administrative units to pay salary supplements. Adds a requirement that participating local school administrative units must commit to full implementation of the program in 35% of schools (was, 50%) in the unit by the 2018-19 school year. Also provides that they must submit a plan showing the schedule for full implementation in at least 55% of schools by the 2019-20 school year (was, 75% of schools). 

Directs the nonprofit corporation to evaluate the program and include feedback from participating teachers and principals and other affected organizations as determined by the State Board of Education in its submitted recommendations to the General Assembly.
