Exhibit 10.15

Amendment Number 1

to the

Scholastic Corporation

2011 Stock Incentive Plan

1. The following amendments are made effective as of May 21, 2013 to the Scholastic Corporation 2011 Stock Incentive Plan (“Plan”):

(a) Section 6.3(a) of the Plan is amended by deleting such section in its entirety and replacing it with the following:

“(a) GRANT PRICE. The grant price per share of Common Stock shall be determined by the Committee, but shall not be less than 100% of the Fair Market Value of a share of Common Stock at the time of grant.”

(b) References to “exercise price” throughout the Plan and related Stock Option Agreements shall be replaced with the term “grant price”.

(c) Article VI of the Plan is amended by adding new Section 6.3(g) as follows:

“(g) AUTOMATIC EXERCISE. The Plan administrator may provide in a Stock Option Agreement or otherwise that any Stock Option outstanding on the last business day of the term of such Stock Option (“Automatic Exercise Date”) that has a “Specified Minimum Value” shall be automatically and without further action by the Participant (or in the event of the Participant’s death, the Participant’s personal representative or estate), be exercised on the Automatic Exercise Date. Payment of the grant price of such Stock Option may be made pursuant to such procedures as may be approved by the Plan administrator from time to time and the Company shall deduct or withhold an amount sufficient to satisfy all taxes associated with such exercise in accordance with Section 12.4. For purposes of this Section 6.3(g), the term “Specified Minimum Value” means that the Fair Market Value per share of Common Stock exceeds the grant price of a share subject to an expiring Stock Option by at least $0.50 cents per share or such other amount as the Plan administrator shall determine from time to time. The Plan administrator may elect to discontinue the automatic exercise of Stock Options pursuant to this Section 6.3(g) at any time upon notice to a Participant. The automatic exercise of a Stock Option pursuant to this Section 6.3(g) shall apply only to a Stock Option award that has been timely accepted by a Participant under procedures specified by the Plan administrator from time to time.”

(d) The Plan Administrator may offer to a Participant to amend any Stock Option Agreements outstanding on the date of this Amendment to incorporate the automatic exercise provisions of new Section 6.3(g).
