Master List for Z

Screen Shot 2014-02-09 at 11.07.45 PM

This list contains a notation for every homeschool-related entity I have researched. Company and/or product names are shown according to the standard process for alphabetizing (i.e., if a title starts with A or The, the article is excluded for alphabetizing purposes, and names of individual people are listed by Last Name, First Name).

I strongly recommend carefully reading all notes when considering any of the products. But to summarize my definitions for clarity here:

Independent (IND) = These companies have not changed anything in regards to the CCS/NGSS/C3 and intend to remain independent of the initiative. They may or may not know of ways in which their materials happen to somehow match some aspects of the CCS/NGSS/C3, but any such connections are purely circumstantial and the providers do not endorse/promote the initiative.

Correlated (COR) = Each of these companies is correlated to - which is different than explicit alignment with - the CCS/NGSS/C3. Correlated providers did not make content changes in order to become "aligned" and, in many cases, have indicated concerns with the initiative. However, they do note (usually on their websites) where/how their materials - as written - correlate with aspects of the CCS/NGSS/C3. In other words, they promote where/how they match the CCS/NGSS/C3, but have not actually changed their content to align.

Ancillary Connections (ANC) = Each of these companies has an ancillary connection to the CCS/NGSS/C3. In most cases, the publishers have indicated a preference for maintaining educational independence from the CCS/NGSS/C3 initiative. However, their resources - usually "package programs" - do incorporate some books from explicitly aligned publishers and/or links to explicitly aligned material from other sources. Thus, a child using a resource with an ancillary connection as designed (i.e., without purposeful substitutions made by a parent) will be exposed to some CCS/NGSS/C3 content.

Explicitly Aligned (EXP) = These companies have indicated that they have chosen to explicitly align their materials with the CCS/NGSS/C3. Some have made relatively small changes, and others have completely overhauled their products - or were even initially created based on the initiative. However, in all cases, conscious content changes were made to accommodate the CCS/NGSS/C3.

Other Responses (OTH) = Each of these companies either needs more time to formulate an official response, has indicated that it will only share its position with individual parents, is not interested in sharing its view at all, or did not respond after many attempts to elicit a reply. Check the list itself for details about each entity.

Awaiting a Response (WAIT) = Each of these companies has been queried, but has not yet sent a reply.

Suppliers/Distributors (SUP) = Unless otherwise noted, these companies do not publish any of their own materials or actually produce curriculum and educational products. Instead, they merely sell resources from a wide variety of other outlets, serving as suppliers/distributors. As such, they have not been queried in regard to the CCS/NGSS/C3. And to my knowledge, they all sell a wide variety of materials – whether independent, correlated, ancillarily connected, or explicitly aligned – without regard to any resource's CCS/NGSS/C3 status.

The site is very mobile-friendly, but the third column of the embedded listings may appear to be cut off on some phones. If that happens, simply turn your phone sideways (i.e., to "landscape" position) to see everything in all three columns.



Zane Education EXP Zane Education advertises that “all videos provided in [its] online educational video library have been developed specifically to meet the requirements of the National, State and Common Core curriculums.”
Zaner-Bloser EXP Zaner-Bloser advertises its alignment with the CCS.
Zazzy Learning Games IND
Zeezok Publishing IND The publisher of Zeezok materials has not read the CCS and is not inclined to change anything in his materials for the CCS. After he eventually reads the CCS, he may “update” his materials if he “feel[s] there is something of worth included in them that we are missing,” but he has no immediate plans to do so.
zeroBio IND zeroBio is aligned to the Ontario (Canada) science curriculum.
Zinn Education Project IND
Zion Academy of America IND Zion Academy uses Accelerated Christian Education (ACE) and ILS Market materials, both of which are independent of the CCS.
Zoe & Sozo Publishing

Zombie-Based Learning COR Zombie-Based Learning is not correlated standard by standard to the CCS/NGSS/C3. But it is “broadly...designed to the Geography for Life Version 2 Standards...[which] are very in depth and informed the C3 standards...” And “for Common Core ELA, there is certainly a lot of connection...[as]...ZBL had a third party do a report on common core alignment.”
Zome Geometry EXP
Zometool EXP
Zondervan (Harper Collins) COR Zondervan is “working to support [the common core standards] by offering a diverse variety of books for every grade level, making it easier for educators, librarians and parents to find Common Core-compliant books.”
Zoobean IND
Zoobooks Publications IND
Zoo-Phonics COR Zoo-Phonics has not changed its content for the CCS, but it does show correlations.
Z-Twist Books SUP
Zui (and KidZui) OTH Zui was contacted multiple times - at least seven over the course of several months – and did not respond to any query. I cannot speculate as to why it has chosen not to reply, and I have no discernible way of knowing its position on the CCS/NGSS.
