Unfortunately the April 2018 issue of the journal contained two errors in this article. Firstly, an incorrect version of Figure 1 was included. The proper version of this figure appears here:

Note: Figure 1 is reprinted, with minor modifications, from Hornberger (1994), with permission from Multilingual Matters, UK.

Figure 1 Language planning and policy: An integrative framework of approaches, types, and goals

Secondly, the following sentence failed to properly incorporate a requested change from the author:

Original text (page 161):

Bottom-up language planning for Indigenous languages in educational contexts may make use of economic and practical resources top-down policy provisions for economic and practical resources to put Indigenous languages in school (Ferguson 2010), present an explicit alternative to top-down policies created by outsiders in international education development contexts (Nagai 1999), or even develop Indigenous language education in spite of lack of top-down policy support (Patrick, Budach & Muckpaloo 2013).

Correction:

Bottom-up language planning for Indigenous languages in educational contexts may make use of top-down policy provisions for economic and practical resources to put Indigenous languages in school (Ferguson 2010). It may also present an explicit alternative to top-down policies created by outsiders in international education development contexts (Nagai 1999), or even develop Indigenous language education in spite of lack of top-down policy support (Patrick, Budach & Muckpaloo 2013).

The Editor apologises for these errors.
