I've been practicing for the Praxis II Math Content exam next Saturday (March 14th). I know that Indiana requires a scaled score of 136 to pass. Does anyone know what kind of raw score is required to get this scaled score? I haven't been able to find jack-squat for info on how the raw score gets converted to a scaled score.

Thanks,

MathManTim

136/200 = 68%

Thank you Captain Obvious!

From some of what I've read, though, I get the impression that it's not that direct. For example, I thought I read that the minimum score was 100 and the maximum 200. If that's true, then 136 would be only 36% correct, and that seems astonishingly low for a passing score...

Thanks,

MathManTim

Wow: I didn't know any teacher test allowed a scaled score that low. (Come to find, though, that some states may allow lower scores than that, or did as of 2006: see http://eduinsights.blogspot.com/2006/07/highly-qualfied-math-teacher.html). The test being in math, though, it's perhaps less surprising: if the pool of qualified candidates is smaller than the number of jobs available, the pressure is on to reduce the qualifications. And I believe the bulk of the scores on teacher tests were set when it was anticipated that there would be a shortage of teachers.

Scaled scores exist so that each version of a given test represents, overall, an equivalent level of effort and proficiency: it's much easier to weight questions differentially than it is to write questions that are exactly equivalent in difficulty.

I was reading that same blog post earlier today. As I've been reviewing for the test, I've been surprised at how relatively elementary the questions have been. Nothing at all like the Math GRE. Some of the questions have thrown me a bit because I literally haven't seen some of the topics since high school (15 years ago). For the past few years, my math education has been much more proof-oriented than computation-oriented.

In my practice exams, I've been averaging about 42-45 out of 50 on the raw score. If the relation between the scaled score and the raw score is linear, then I should be okay. Otherwise, heck, maybe a scaled score of 136 really is 40 or so out of 50 correct.

That's what I'm hoping for my area. I don't know, though...it seems like my alma mater graduates a fair number of math teachers into the local job pool. Oh, well. I guess I'll find out this Saturday at the job fair.

As to the pool of qualified candidates, I'm talking historically, Tim, not presently. And, in partial contradiction of the blog's assertions, some of the other states' tests are rather less heavy on computation: see the sample items at http://www.cset.nesinc.com/CS_testguide_Mathopener.asp.

He probably won't find out how he did for about a month. I took the middle school math test last March and missed it by 2 points. A passing score for here was 148.

Tim hope you passed!!

Yep, I took it last Saturday. I'm pretty sure I passed, though I would be floored if I got a perfect score. For the record, the test was harder than the sample exams in the preparation books I bought. In retrospect, I should have spent a little more time reviewing matrix theory.

Oh, and I'm changing my name on this board temporarily. In honor of my officially passing Praxis I, I am changing my name from MathManTim to Math-(Who's The Man! :thumb: )-Tim for the next 24 hours.

Hey MathManTim

I'm studying for the Praxis II Math Content Knowledge exam right now, (0061), and I was wondering what study materials did you use? Mostly old textbooks for questions maybe? I'm taking the test April 24th. If you don't mind me asking, how did you prepare for this exam? Did you ever find any answers elsewhere regarding the raw vs scaled scores? I need 136 to pass, but I don't know what that translates to as far as number correct. When you took it, and felt you did well, was it a high scaled score? Do they tell you how many you missed to get that score? Any tips or advice would be greatly appreciated. Any suggestions where to find practice exams? Thank you.

As was noted earlier, Praxis exams' scales run from 100 to 200. Functionally, 100 is zero; there's no scenario under which I can imagine that 136 amounting to more than 40% correct.

I took the test in Jan, for the first time and I got 17/50 right 34% and I only need 130 to pass the test. My score was only 110, so the raw-to-scale score is very confusing. I thought with that many correct I should have at least got a 125-130.....puzzled!

Hmmm... Well, one of the reasons that scaled scores are used is to try to ensure that any score of 130 represents the same level of achievement, no matter which version (form) of the test is given. Since, however, it's very difficult to write test questions that are of exactly equivalent difficulty, the algorithm that converts raw scores to scaled scores contains "fudge factors" (so to speak) that weight harder questions more heavily and easier ones more lightly. The difference in weighting could account for the variance you see.

Did the official score report give any insight into specific areas to work on?

I took this test in March for the first time and passed although the score wasn't that great but who cares, at least I don't have to take it again. I thought the exam was pretty hard and I didn't have enough time to finish and just ended up guessing on a lot of questions. My score was weird and I don't even think was reflective of how well I know the subjects because I scored really low on algebra, which I think is the easiest subject for me or at least the one I remember most from high school, long time ago. I used the Cliffnotes book although many people say that the practice tests in that book are a lot easier than the actual test and I concur. I also purchased some practice tests from a website for I think \$30 at the last minute but that was kind of a waste of money as the tests wasn't even reflective of the actual test I took so it really threw me off because I got totally different questions. I also used a math website to review my math. And let's just say I think all that time spent studying was pretty pointless and wish I wouldn't have spent so much time on it as I don't think much of what I studied helped all that much. I would say the best review is the Cliffnotes book even though the practice tests are easier than the actual exam, the book gives a pretty good overview of what is covered and you can use that as a study guide.

The exam scale is from 100-200. There are 50 questions. Based on my score, seems like to get at least 136, you need to get less than 30 questions correct although I'm not sure how many less but based on LaTeacher10's post, more than 17 so maybe 25 or around there?

im not really nervous cause I did well on the GRE quantitative section without studying and I studied a bunch for this! So yea, Im reviewing my discrete math and trigonometry since i havent seen that stuff in a while.

Thanks for Encouragement Groupie...Minimum Score for my state is 136, I think I should surpass this.

plurple, you call this a hijack??

But, seriously... take a look at the coverage for each test that's indicated in the official online materials - the Frameworks doc for WEST-E, the list of topics on the Tests at a Glance doc for 0061. I'm guessing that there isn't much that Praxis covers that WEST-E doesn't, so chances are pretty good that you're in fine shape.

Well, the GRE quantitative section is extremely easy and is just like the SATs so don't think it can really be compared with the Praxis II math.

I took the praxis II math 0061 content knowledge test last April. It was not my first praxis II exam in which I had the pleasure of taking. (Sarcasm implied) I am one of many of ets's disgruntled customers. My complaints are endless when it comes to this company as well as my states "standard" passing score. If anyone else is licensed in the state of Virginia you can empathies with me.
I am a licensed physics teacher. I took the praxis II in physics 3 times. It’s a nearly impossible test to complete in the time allowed, not mention no equations are given and no calculators are permitted. Only after teaching for two years was I able to achieve a passing score; and I have a BS in Physics. Virginia requires a passing score of 147 for both physics and math. I have now scored a 146 on the physics test and again last April on the mathematics test.
As far as "raw score vs. scaled score" goes I believe it’s a bunch of CRAP. ETS's "statistical" algorithm, which is not disclosed to a test taker, is a scam. I received a raw score two different times on two different tests in which I should have received a passing score. However, ETS's scaled score placed me one point below my states passing score. Coincidence, I think not. I have heard too many stories from other co-workers and post graduates who score one point below their states passing score. The sad truth to my story and my ultimate complaint is that ETS is keeping well qualified, young, enthusiastic teachers out of the classroom.
I will take the math praxis II again at the end of July. I pray my study efforts these past two months pay off. My job depends on it and ETS’s scoring algorithm.

146 is a passing score in math 0061 in every state (that uses Praxis II) *except* Virginia. I'm sorry.

Are you saying it's a scam from ETS to make people pay another \$80 to take the exam? That stinks.

Best to you.

That's 146 on a scale from 100 to 200, though: most of us have been in college classes that we'd have flunked with a score like that.

teachphysics, my experience of teacher tests is that when no calculator is allowed, the math usually is manageable by hand. In some cases, in fact, the math can be finessed - I'm thinking of the classic math problem early in the SAT that involves some long and hideous sequence of symbols that's raised to the power 0: the cute trick here is that a number raised to the power 0 is simply 1.

The Praxis content knowledge tests are multiple choice tests, if memory serves. Do you give your students multiple choice tests? If so, how do you guide students who panic?

If in doubt "_" and stick with it statistically the odds are in your favor. I’m just kidding. I'm too scared to even sign-up for the test! I know this will work out for your benefit teachphysics. I have no room to jest, my HS Physics teacher made me cry. All I remember is a slope, a plane, a force and a ball. Wait! Oh no! Is that a tear? No, really good luck!

I believe if your raw score is boarder line with your states passing score then ETS will more than likely make you retake the exam. I purchased their study guide which claimed that a raw score of 28 of 50 would result in a scaled score of 146. I got 31 questions right which means ETS deemed the particular exam I took easier than other exams they developed. ( ETS website claims that this is how their scaled algorithm works.)

I took the Math Praxis 0061 this morning and it was nothing like any of ETS's "practice" or "test at a glance" or even the ebook I purchased from the ETS website that was a retired test. It was ALOT harder. The difficulty level of the questions was a step or two up from all of the practice problems I completed. Not that I thought the test wes going to be easy, but it would have been nice if the difficulty level of the questions was comprable to the practice questions I purchased from both ETS and another website. Very misleading! Now I'm just hoping for the best because I have absoluetly no idea how I did. If I took this test right out of college, maybe I would have done better. Unfortunately I've been out for 15 years this past May, so I am at a major disadvantage. I will be student teaching in the fall, so if I have to take the test again, it won't be until after the fall semester. In the meantime I'll just hope for the best!

So...if my state requires a scaled score of 156 ....what do you think?

So, my state, Colorado, requires a scaled score of 156. They prefer you take a state developed test called the PLACE which is much easier to pass but not accepted by other states.

I wanted to take the PRAXIS in case I ever more (not likely) but it seems that if a 147 in VA is really difficult then a 156 will be almost impossible.

Thoughts?

Go with PLACE, since it's what you want locally; in most states, if you have a valid license when you move, you're eligible to teach for one to three years on a provisional license for that state while you sort out the new state's specific testing requirements. Bear in mind also that Praxis II is not accepted by all other states; you'll need to take a non-Praxis exam if you move to Arizona, California, Florida, Georgia, Illinois, Massachusetts, Michigan, New Mexico, New York, Oregon (as of next year, I believe), or Washington state (and I'm probably not remembering a few).

I don't know why the ETS practice problems seem to be easier than the actual exam, but I hear that a lot. I have corresponded with Jerry who teaches college math and who runs www.praxisiimath.com/praxisg
and his philosophy is just the opposite - practice on problems that are likely to be harder than the actual exam. He says it is like a baseball player warming up with a weight on his bat, so that when he actually gets up to hit he uses the bat without the weight and it feels much lighter.

Praxis 0061

I am going to take the Praxis 0061 next month (January ) , I need a score of 151 or more to pass . How can I prepare for this exam ? ,I have graduated from Engineering college about 25 years ago and I am a substitute teacher for more than 7 years now . I need to pass this exam as the first step to be certified as a math teacher . My GPA is 2.5 that is why I have to score 10 % more than the passing score (137) in New Jersey .

Forgot to spell out the asterisk

Use the online test description - which you can download from ETS's New Jersey page or from the pull-down menu on a page whose title is something about test preparation* - to figure out what the topics are. Then let me suggest going through the relevant videos at http://www.khanacademy.org/#browse.

*Please forgive the vagueness. I've worked a bit with Praxis, but not very often in the last eight years.

I love that with NJ. I guess it makes some sense. Actually a reward for a higher GPA.

I am studying for the MS Science and Physical Science test in Jan. Yes taking two at one time.I have so far been impressed with the xamonline.com book. Which involves using one book.

ORder xamonline from Amazon ad that seems to be the cheapest place.

I'm also taking it next saturday and I live in Nj. I'm taking it at william patterson. I've been studying some of my old highschool books so far, and I do have some college textbooks. I've studied algebra 1 tests and quizzes and Read a good portion of My geometry teachers edition. But I feel like i'm not really studying the right material or the right difficulty level. It seems I am just refreshing the basics, but not necessarily applying them. I downloaded the test at a glance, and paid for the ets studyguide. After reading some posts, it seems the ets study guide isnt really a good prep for the exam. I am thinking about purchasing from Jerry who is a professor and has had experience taking exams and developed a good study guide (Since im new it wont let me post the link). I have a cumulative gpa of 2.87 so I think my required score is less but I'm still concerned, I haven't seen this material in quite some time. What do you guys suggest? Am I on the right track as far as gathering materials? Do you know anyone that used this study guide from Jerry and had success? Thanks in advance.

Raw to Scaled Score from ETS

I purchased the 0061 practice test (PDF) from ETS. I just registered for March 10 to take it, my cutoff for passing is 136 here so I hope I can remember all of this (I just moved between states - hold a CA SB2042 single subject mathematics teaching credential, BS Math, MSEd...apparently that isn't enough - gotta take PRAXIS and CPR/AED, yay).

Anyway, there is a conversion chart so I thought I'd share it with you all, since there seems to be some confusion. I think the scaled score/raw score chart depends on each test, but this might give you an idea:

Raw Score (correct out of 50 questions) = Scaled Score (between 100 and 200)

0=100
1=100
2=100
3=100
4=100
5=100
6=100
7=100
8=100
9=100
10=100
11=100
12=100
13=100
14=102
15=105
16=109
17=112
18=115
19=118
20=122
21=125
22=128
23=131
24=134
25=138
26=140
27=143
28=146
29=149
30=151
31=154
32=156
33=158
34=160
35=162
36=165
37=167
38=169
39=170
40=172
41=174
42=176
43=178
44=180
45=182
46=184
47=186
48=189
49=192
50=194

So for me, I would need to get 25 questions correct (minimum) to pass - so a perfect 50%. Nice!

I am nervous about the posts stating the practice test from ETS is easier than the real deal...but needing approx. 50% correct is reassuring. Hopefully I can pull that off.

Good luck and please share any test taking tips! I hope to pass this one on the first try so I can get my credential cleared.

This scale is an approximation. Scaled scores exist because it's very hard to write even two questions that are exactly equivalent in difficulty, let alone a test full of them - so the algorithm that converts raw scores to scaled contains fudge factors that bump some questions up in value and some down. The idea is that each score of 137 (for instance) should represent the same level of achievement; the cut score is chosen for each state to represent the minimum level of proficiency that state wants from each beginning teacher.

If you passed CSET Math, I don't think Praxis II math exams will hold much terror for you.
