Informed Teachers Change Lives

Proven professional development for teachers of language and literacy.

Teachers who understand the science of reading can transform their instruction and ensure 95 percent of students learn to read. It’s true teachers are more essential to student success than any other aspect of schooling. They, not programs, teach students how to read. Yet a study of most teaching institutions found only 49 percent actually prepare teachers with all five essential components of literacy instruction: phonemic awareness, phonics, fluency, vocabulary, and comprehension. *Additionally, the 2019 National Assessment of Educational Progress, NAEP, study found 66 percent of U.S. fourth grade students are not proficient readers. Reading requires multiple parts of the brain learning to work together. Teaching reading requires a deep understanding of the science behind how we learn to read, why we spell the way we do, or how phonemic awareness and phonics lead to comprehension. Without this, teachers are left feeling ill-prepared. That’s why LETRS ® bridges decades of evidenced-based research into classroom success.

Voyager Sopris Learning, Inc. Privacy Policy

This site provides you with access to the Voyager Sopris Data Management System. This system is an integral component of Voyager's curriculum products and provides valuable reporting, instructional recommendations, and other resources used by teachers and other instructional leaders in conjunction with Voyager's curriculum with the goal of improving student performance.

This statement describes the privacy and security practices Voyager Sopris employs for this site. We have adopted these practices to protect you, the students, and the school district, and to enable each of us to comply with applicable legal requirements. Use of this site requires district acceptance of the practices outlined in this statement.

Two types of personally identifiable information are used on this site: your personal data and student data .

Your Personal Data Collection : Voyager Sopris collects information from you as you use this site. For example, you must enter certain personally identifiable information, including your name, e-mail address, and phone number. We use this information to verify your identity and prevent unauthorized access to your account and to contact you in connection with your use of this site.

In addition to the information you provide, Voyager Sopris collects information about your use of this site through tracking, cookies, and log files, as described in our general Terms of Use statement.

Protection : Because you enter your personal data, you control its accuracy. If you discover that your personal data is inaccurate or if it changes, you may make corrections by notifying us at [email protected] or 1.800.547.6747. We will not share your personal data collected through this site with third persons without your consent. However, your personal data will be available to authorized users from your school district who have permission from the school district to access it. We will not use your personal data collected through this site for any purpose other than providing you with access to this site and the associated services. We will use the same security to protect your personal data that we use to protect student data collected through this site.

Student Data As you use this site, you will enter student data or interact with student data that has already been entered. Federal law (the Family Educational Rights and Privacy Act, "FERPA") allows a school district to release student records to an organization that is "conducting studies for, or on behalf of, educational agencies or institutions for the purpose of developing, validating, or administering predictive tests... [or] improving instruction."

However, FERPA requires limitations on disclosure of those records and implementation of appropriate security measures to protect those records. To help your school district comply with FERPA, Voyager Sopris has adopted certain practices, and requires that educators using this site fulfill certain responsibilities to safeguard student data. The following statement explains our practices and your responsibilities regarding the student data you enter on this site.

Student Data Security and Confidentiality Statement Purposes of Data Entry : You control what student data is entered on this site. Student data entered on this site should be limited to information that is relevant to the legitimate educational purpose of improving student performance. We will not ask you to enter, and you are instructed not to enter, data about students that is not relevant to this legitimate educational purpose.

Therefore, only a minimum amount of personally identifiable student data required for the setup of the system is requested. We require student first name, student last name, and student identification number. Additional data, not specific to the student, is also required to complete system setup, including the teacher first and last name, class name, grade level, and school name. Student demographic data, for the purposes of optional disaggregated reporting, is requested separately from the initial setup data and is obtained only with written permission from your district.

Use, Disclosure, and Storage: We will use the student data to provide the services to your school district. We will not keep the student data after you or the school district instructs us to delete it. You may not disclose or otherwise use the student data entered on this site for any unauthorized purposes.

We will only disclose student data to authorized employees or representatives of the school district, and will not knowingly disclose the student data to any third person without express written authorization. When, at the request of the district, we acquire assessment or other information, including personally identifiable student data, from a third party source we treat that information with the same confidentiality and security safeguards as though it were provided directly by the district. Additional agreements may be required by the third party to authorize transmission of data to Voyager Sopris.

Your district may from time to time request that Voyager Sopris provide student data to third parties of its choosing. We will do so with written authorization, which acknowledges that Voyager Sopris is providing that data as your district's agent and that once the data is received by the third party, Voyager Sopris no longer has any control over the use or disposition of the data.

We may also use aggregated data in our research, product development, and marketing. That aggregated, non-personally identifiable data (e.g., summary or statistical data) may be shared with third parties. However, we do not use personally identifiable student data to market any products or services directly to students or their parents.

In the event that Voyager Sopris wishes, from time to time, to release aggregated data that identifies your school or school district by name, Voyager Sopris will enter into a separate agreement with you to authorize release and publication.

Data Quality : You are responsible for keeping the student data that you enter accurate, complete and up-to-date. If you recognize that student data is inaccurate, incomplete, or out-of-date, you are responsible for correcting it. If you experience problems making corrections to student data, please notify us at [email protected] or 1.800.547.6747 and we will assist you with making corrections.

Security Safeguards : We are committed to protecting student data against unauthorized access, destruction, use, modification or disclosure. Protecting student data requires efforts from us and from you. We will implement reasonable and appropriate safeguards when collecting student data from you and when storing that student data in our database and you will observe our security safeguards and exercise reasonable caution when using this site.

• Only Voyager Sopris employees who are authorized to handle student data are able to access the Data Management System.
• A teacher will only be able to see data for his/her class.
• A Principal, Coach, or other authorized School User will be able to view all data at a given school.
• An authorized district-level employee, such as an Instructional Coordinator or Superintendent, will be able to see all data across the district.
• Each authorized school official is given a Userid and Password valid only for the duration of the academic year, including a summer program if applicable. You must safeguard your Userid and Password, and not permit any unauthorized access to student data entered or kept in the Voyager Sopris system.
• Upon written request by the district, Voyager Sopris will destroy any student data for districts who no longer participate in a Voyager Sopris reading program. Voyager Sopris will provide written verification that the data has been destroyed as requested.
• If a district has not used any Voyager Sopris product for a period of ten years, Voyager Sopris will provide written notice that the student data pertaining to their district will be destroyed, unless the district requests the records be kept. Upon destruction, Voyager Sopris will provide written verification that the data has been destroyed.
• Voyager Sopris uses industry standard server and network hardware and software to ensure that data is protected from unauthorized access or disclosure.

When you use this site, you consent to our privacy practices and agree to accept the responsibilities outlined in this statement.

Download brochure

Research shows that only 35% of students are reading proficiently, but 95% of students CAN learn to read when instruction is based on the science of reading. And while teachers are the most essential factor in student success, only about half of teaching institutions effectively prepare teachers for literacy instruction. Teaching reading requires a deep understanding of the processes and science behind it. LETRS is the professional learning program rooted in the science of reading that empowers teachers.

What LETRS participants have to say

"I enjoy the way LETRS is structured, especially the length of the videos. It is easy to chunk and return to it with a busy schedule. For my own learning, I like to read it, take notes and then do the videos, etc. before class. It helps solidify the learning for me. Others in my class like to attend online class first and then read."

NASA's Voyager 1 spacecraft finally phones home after 5 months of no contact

On Saturday, April 5, Voyager 1 finally "phoned home" and updated its NASA operating team about its health.

NASA's interstellar explorer Voyager 1 is finally communicating with ground control in an understandable way again. On Saturday (April 20), Voyager 1 updated ground control about its health status for the first time in 5 months. While the Voyager 1 spacecraft still isn't sending valid science data back to Earth, it is now returning usable information about the health and operating status of its onboard engineering systems. 

Thirty-five years after its launch in 1977, Voyager 1 became the first human-made object to leave the solar system and enter interstellar space . It was followed out of our cosmic quarters by its space-faring sibling, Voyager 2 , six years later in 2018. Voyager 2, thankfully, is still operational and communicating well with Earth. 

The two spacecraft remain the only human-made objects exploring space beyond the influence of the sun. However, on Nov. 14, 2023, after 11 years of exploring interstellar space and while sitting a staggering 15 billion miles (24 billion kilometers) from Earth, Voyager 1's binary code — computer language composed of 0s and 1s that it uses to communicate with its flight team at NASA — stopped making sense.

Related: We finally know why NASA's Voyager 1 spacecraft stopped communicating — scientists are working on a fix

In March, NASA's Voyager 1 operating team sent a digital "poke" to the spacecraft, prompting its flight data subsystem (FDS) to send a full memory readout back home.

This memory dump revealed to scientists and engineers that the "glitch" is the result of a corrupted code contained on a single chip representing around 3% of the FDS memory. The loss of this code rendered Voyager 1's science and engineering data unusable.

The NASA team can't physically repair or replace this chip, of course, but what they can do is remotely place the affected code elsewhere in the FDS memory. Though no single section of the memory is large enough to hold this code entirely, the team can slice it into sections and store these chunks separately. To do this, they will also have to adjust the relevant storage sections to ensure the addition of this corrupted code won't cause those areas to stop operating individually, or working together as a whole. In addition to this, NASA staff will also have to ensure any references to the corrupted code's location are updated.

On April 18, 2024, the team began sending the code to its new location in the FDS memory. This was a painstaking process, as a radio signal takes 22.5 hours to traverse the distance between Earth and Voyager 1, and it then takes another 22.5 hours to get a signal back from the craft. 

By Saturday (April 20), however, the team confirmed their modification had worked. For the first time in five months, the scientists were able to communicate with Voyager 1 and check its health. Over the next few weeks, the team will work on adjusting the rest of the FDS software and aim to recover the regions of the system that are responsible for packaging and returning vital science data from beyond the limits of the solar system.

evw said: I'm incredibly grateful for the persistence and dedication of the Voyagers' teams and for the amazing accomplishments that have kept these two spacecrafts operational so many years beyond their expected lifetimes. V-1 was launched when I was 25 years young; I was nearly delirious with joy. Exploring the physical universe captivated my attention while I was in elementary school and has kept me mesmerized since. I'm very emotional writing this note, thinking about what amounts to a miracle of technology and longevity in my eyes. BRAVO!!! THANK YOU EVERYONE PAST & PRESENT!!!
